If you haven’t read previous part, it’s right here –  US Diaries Part 2.

Why do we click pictures? To frame moments, walk down memory lanes and reminisce about events that once awestrucked us. This post is a living example of how pictures help you to relive memories that would have otherwise been lost.

Luckily, I was able to get 4 days of vacation to visit California. California is a beautiful city and my main interest was to wander in the streets of Disney Land and Universal Studios. A dream of decade to see Sleeping beauty castle and roam around in Harry Potter Park with a wizard wand in hand was about to be fulfilled.

Spirit Airlines sucks

Having spent a huge chunk of money in shopping and local traveling, I was reluctant to burn another big hole in my pocket. Though I make exceptions if it comes to my family or my hobbies or sometimes my friends too, being raised in middle class,  my brain is hardwired to see value for money. We got our tickets from Seattle to Los Angeles booked at cheaper rates. My plan looked something like:

One day in San Diego, Visit Disney Land and Universal Studios in LA.

Our plan screwed up when Spirit Airlines managed to fly late by 5 hours the same day I was to visit Disney Land. Spirit Airlines allows only 6 kgs cabin luggage, majority of which was occupied with my camera and its equipments. I managed to get one fine picture depicting bad weather of Seattle while roaming around impatiently at the airport.

Wonders of California

The first thing that comes to my mind when someone talks about California is that it is hotter. From Seattle’s chilling winter where you need layered wear to LA’s summer, the change was very noticeable. One fine evening in Seattle, on the pavement outside Cheesecake Factory, I was waiting for my friend and slightly bored as she was running late. That’s when I witnessed the second snow fall in my life. Seattle is said to be depressing in winters. Well, didn’t look like it to me.

One of the best thing in California I observed was all happy faces around. It makes me wonder, “How can so many happy people exist at one place?”.

Day 1: Disney Land, LA

We reached LA at ~4:00 PM. It was 4:55 when we reached Disney Land. We were very grateful to book tickets online. It had already started getting dark.

Dreams do come true

Sleeping beauty castle was always in my To visit list. And people there were as crazy as I was after witnessing this magnificent beauty. Even the huge crowd couldn’t dampen the excitement. Happiness was in the air.

The castle looked even more magnificent when it got dark. As magical and brightening it could be, its starking contrast had the power to stop you from taking your eyes off it.

Picturesque

Every part of the park is quite picturesque. If you love taking pictures, it would be hard to put camera down for a moment. The park was full of families and there were so many kids around. It was funny to know that there was a separate parking for strollers and it was full.

They celebrate Diwali each day

Isn’t it exciting that they celebrate Diwali every day? It was the kind of fireworks we get to see at the start of each of Disney’s movie. It was beautiful and kind of spell bounding.

“Sleeping beauty castle in fireworks”

One of the things I remember very well from my trip to Disney Land, LA is the park being lit up in fireworks for around half an hour. This is probably the best fireworks I’ve witnessed in my life so far. Due to the huge crowd, trying my best to grab the best spot and not owning a wide angle lens back then, this is the best shot I could get. As you might have observed, in the center, lies there the peak of very famous Sleeping Beauty Castle.

Electric Parade

They mark the end of day with an electric parade where you get to see almost every Disney character marching on the narrow roads with awestruck presentation.

The magical music

Disneyland seems particularly fond of Mozart. Being a classic music fanatic, it was pleasant to listen Mozart’s famous Allegro everywhere. It added flavors to the magical feeling. You can listen the music here.

It is really hard to imagine someone returning not happy after spending a day in the park. It was a very nice experience indeed for 100 USD.

Day 2 : Universal Studios Hollywood, LA

It wasn’t a difficult call to decide which one of the Theme Parks I wanted to spend 2 days in. I booked 2 days ticket for Universal Studios for 129 bucksI knew one day was not enough to quench my thirst for Harry Potter.

If you hail from India and happen to visit Ramoji film city in Hyderabad, Universal Studios is like Ramoji, just a thousand times better. It has theme parks and attractions of many famous characters. Minion Mayhem and the girl’s house, Transformers, Simpsons, Shrek, Walking dead, Mummy, Spongebob and the most important The wizarding world of Harry Potter.

The wizarding world of Harry Potter

If you are a No-Maj and are reading this, let me warn you muggle. What you are gonna read next is not everyone’s cup of tea. To feel the magic and connect with this fantabulastic world, it needs an exceptional level of imagination and a deep dive into the story. If not, bear no delusions, it would be just another story and another park for you. Chances are you may not understand Potterheads and their craziness.

Magical feeling

A magical experience is all I would say. Even 2 decades of Harry Potter universe hasn’t lessened the craziness, The crowd was ecstatic and delighted. Their glittering eyes were reflection of dreams coming true. Being a person who has grown up with Harry Potter waiting relentlessly, I felt like going back into childhood.

Hogwarts, Hogmeade, Platform 9 3/4, Hogwarts Express, Diagon Alley, Three Broomsticks minus Madame Rosemerta, Ollivanders, Hagrid’s hut, Honeydukes, Zonko’s joke shop, Hog’s Head, Butterbeer cart, Post office. The park has got everything in attention to detail. I couldn’t have imagined it any better. People rushing in the narrow streets of Diagon Alley was as if it came from book alive.

Hogwarts Express

The school of magic

I oftentimes wonder, how different life would be, how full of magic and fantastical beauty, if my Hogwarts letter would have arrived.

Ollivanders, makers of fine wand

Ollivanders, makers of fine wand since 382 BC, helping eleven years old getting their first wand. He very well portrayed the scene from the first movie where Harry gets his wand. It was as if I was teleported into the movie and watched it happen. As a matter of fact, wand chooses its master. When spell was read with wrong wand in hand, the shacks broke. The setting couldn’t have been more perfect.

I got The Elder Wand, magnificent and powerful.

Hogwarts Express

Hogwarts Express about to leave from platform number 9 3/4.

Gringotts: The wizards’ bank

Enter, stranger, but take heed
Of what awaits the sin of greed
For those who take, but do not earn,
Must pay most dearly in their turn.
So if you seek beneath our floors
A treasure that was never yours,
Thief, you have been warned, beware
Of finding more than treasure there.

Gringotts. Wizards’ bank, run by Goblins. Gringotts is the safest place in the world for
anything you want to keep safe — ‘cept maybe Hogwarts.

A quick note on Hogwarts and Hogsmeade. Hogwarts is a magic school where you learn magic and how to control it for greater good. Hogsmeade is a village near Hogwarts where Harry and his friends used to go to chillax after tiring and exhausting exams.

The three broomsticks and Butterbeer

Three broomsticks is a well known pub in Hogsmeade, particularly famous of its delicious signature drink Butterbeer and its beautiful owner Madam Rosmerta.

The three broomsticks – The great feast
Time for some magical food in the Hogsmeade village. It was probably one of the best days of my life so far. Being a huge Harry Potter fan, how could I miss “The three broomsticks”? The famous tavern in Hogsmeade had its own charm. The magnificent dark ambience was perfect for talking in plain sight. It is no surprise why wizards and witches choose this place to hear gossips. Even the place being full of muggles that day couldn’t suppress my goosebumps.

A pint of Butterbeer at Three Broomsticks.
As a fan of wizarding world of Harry Potter since my very childhood, I fantasized about having a taste of Butterbeer. I always thought it would be like magic flowing in my veins. As I grew up and got a chance to have it, I must say it tasted something like Butterscotch. The Butterbeer lived up to its expectations. I could literally find myself diving into the magical world and remembered one of the greatest friendship I have ever known, the friendship of Harry, Ronald and Hermione. Sad part was I had to drink this alone.
I hope someday I will visit there again with my Ronald and Hermione.

Do you remember the roasted chicken Harry used to crave for when he stayed at his Uncle’s place during summers? Or when he used to eat like a hungry beast after long Quidditch practice?
Well, I tried the “Lemon herb roast chicken platter” at Three broomsticks and it was worth all the rumor.

Hagrid’s hut

The second home of Harry, Ronald and Hermione where they used to spend their free evenings when not worrying about Quidditch practices and studies. This is where Norbert was born. The lantern hanging across the wooden door was often used by them in Forbidden forest.

Magic was in the air

A kid practicing trying to rotate cauldron using Wingardium Leviosa spell in Hogwarts. Two kinds of wands they were selling in Ollivanders – Interactive and non-interactive. Interactive ones were real magic and could be used to turn lights on/off, float objects, turn on the water in a fountain, make birds sing and many more such stuffs.

Butterbeer cart

To be continued… In the next post, I will talk more about Universal Studios and San Diego story.

If you are wondering how I ended up at Microsoft, well, it’s a long story and if you have got some time, you can read it here:

Journey of a boy from small town to Microsoft – An untold story Part 1

If you like to read about dreams and goals, you might like my journey. I won’t claim it to be inspiring and motivating. Neither would I claim it to be struggling and unique. I will leave it for you to decide. But everyone has a journey and a story to tell. And this my friend, is my journey.

July 15, 2013

Each year when I wake up in the morning and find Facebook reminding me of this very date, I can’t stop myself to feel happy and grateful. I thank god who has graced my life with all the opportunities & happiness and given me an ability to be good at what I do.

4 years it’s been since I joined Microsoft and it feels like it were only yesterday when I wandered the corridors of the humongous campus for the first time. Days bled off into years. I have seen people come. I have seen people leave. Life moves on. Everyone is replaceable.

If you haven’t read previous part, it’s right here –  US Diaries Part 1

US is a country of dreams. I could see it shining right through everyone’s eyes. I met one person in taxi who played piano and released his own music album. The other guy Chad writes pilots for TV series and is a good photographer. There was another guy who had done some coding. He knew what python and C++ is. He wanted to work at Amazon or Microsoft. Another guy was a lead manager in an MNC and drove Uber just for fun. They don’t care much about the social status. They do what they love to do.

A really nice country where people greet you and don’t expect anything in return. Everyone you meet is so much open to talk without holding any grudge. Believe me, I had some of the best conversations in just a span of 30 minutes or so.

Redmond = Microsoft

I had heard that Microsoft has humongous office in its headquarters, Redmond. Well, it was true. I was amazed by seeing the area in which it was spread. If I say Redmond is Microsoft, it won’t be wrong. 135 buildings.

Microsoft, US culture

Unlike India where people tend to stay late in offices, Redmond is just the opposite. People come early and leave early. You would hardly find anyone staring at work monitor after 6. People are punctual and highly efficient. Well, I could see where that efficiency comes from. They don’t talk much and confine their conversation to mainly professional stuffs. The hours they put in work are really productive. The culture is so well defined that if you stay late, you would have a feeling that you are working in a zombie village. I, personally liked this culture and I easily embraced it. I had free evenings where I could catch some friends over dinner in classy sounding restaurants.

The world is small

It really is a small world we live in. It is not very unusual that while dining or taking a walk in busy streets, I stumble upon someone who happens to know me. Well, it has happened many times in India. But when you face the same in US, you start thinking that the world is really small. I met an old friend while crossing a street in Redmond, stumbled upon another known face in Seattle while dining with a college friend and had a short chit chat with a guy on shuttle, I used to see in dance classes in Hyderabad.

Seattle diaries

One of the exciting thing about Seattle is incessant rains. Rainy season is something people either love or hate. You will hardly find anyone being neutral on it.

Space Needle

If you’re a Windows user, you must have noticed the tall tower with a big circular head on lock screen. What if I tell you, it is much more beautiful when you look it closely? Well, it is a marvelous piece of human architecture. Standing tall at a height of 184 meters, you can see the whole Seattle view from the top. I could manage to get some pics from my DSLR even though it was freezing cold. My finger nails had turned bluish.

The head of tower

The Seattle view point

Standing on the top of Space Needle and experiencing this view was a treat to eyes.

I always wanted to dine at Skycity Space Needle restaurant. Well, who won’t? After all, dining at such a height has a unique magical feeling. You are sitting and eating exquisite food while the restaurant rotates to show you every angle of the city. Sadly, I couldn’t get a booking. It had 2 weeks waiting time.

Chihuly garden and glass

You can’t miss Chihuly garden and glass if you love art while being in Seattle. This place is mainly famous for its exceptional glass arch, mostly attracted by photographers. I met many photographers there and got a chance to flaunt my skills. Visiting Chihuly wasn’t easy due to shortage of time. The place opens at 11 in the morning and I had return flight on the same day at 5. On the top of that, it was raining like crazy. Well then it’s Seattle. Rains are not supposed to crash the fun. Thanks to Hotel Marriott for making special arrangements.

This picture has its own story. Chihuly Garden and Glass attracts a lot of tourists due to its marvelous, eye popping glass arch. I had a chance to interact with many photographers there and it was fun discussing about various aspects of photography. I wanted to capture whole 25 feet long arch in one frame and for this, I had to wait 30 minutes to capture this due to the huge crowd. Funny to say, due to my corporate ID hanging out of my pocket, few of the tourists asked me if I worked there.

North-Bend

Situated at a distance of 30 miles from Redmond, North-Bend is a bliss to eyes. No matter if you are a nature and mountains lover or love long driving on beautiful roads or a shopping spree, North-Bend has got a charm in its own. Built near mountains which are covered with snow in winter, there are many shops where you can enjoy buying stuffs.

The cheese mountain.
I clicked this amazing shot in North Bend, US. Seattle is a beautiful city. Incessant rains, chilly wind, snowy mountain and golden sunshine. A serene heaven for photographers.
It was a sudden plan. The moment I arrived there, the sun was about to set and its dusky golden rays falling on the snow over the top of mountain was giving a perception of molten golden cheese all around.

I am quite fond of keeping a collection of perfumes. When I saw Perfumania shop at the North-Bend, I got a chance to try out all the perfumes I had been researching for years. At the end, I got one of my favorites, one what everyone in US uses, and one which was the choice of the woman who sold me all this.

Heroes of my wardrobe  Recently I have got an urge to keep a collection of perfumes.

Chocolates

A trip to US is not complete until you get chocolates for your loved ones.

In the next part, I would be writing about my trip to Los Angeles and San Diego. Please stay tuned.

I am a CSE Graduate from KIIT University. I joined Microsoft straight out of college. Usually, Microsoft doesn’t visit there, but that year I got lucky.

2 written tests + 3 F2F technical interviews + 1 Skype technical interview

 

Written test 1 (Objective), 30 minutes

First written test was conducted by some third party company. It consisted of 15 objective questions from C, Sorting, Data Structures, Big O, compiler and state machine. We were given 30 minutes. Cut off was 12 out of 15 questions. 77 out of 400 students made it.

Written test 2 (Coding), 60 minutes

Three problems to be solved in 60 minutes with no use of compiler. One problem on Linked List, second on heap and third on array. I coded all problems from scratch including main method. I also wrote flexible methods that could work on any kind of inputs (instead of deleting nodes from 4 to 6, it would delete nodes between ‘M’ and ‘N’ ) and handle all corner cases. The result was announced after 20 days. 30 out of 77 made it.

F2F Interview #1, 60 minutes

We were interviewed in groups of 6. Each one of us in a group was given same problem to solve. I couldn’t code the perfect solution in an hour. All I had discussed 6 different ways to solve the problem. I was afraid that I might be rejected in first round. The interview lasted for 60 minutes.

14 out of 30 were selected.

Every evening on the roof top of my hostel in Delhi, I used to see the shining airplanes going off into the thin air and wondered when I would get a chance to fly in one of these with my own capability. While that dream was fulfilled the moment I joined Microsoft, I started wondering to fly to United States in the best of airlines to feel how is it like to be in the most powerful country in the world..You can say that my dreams always get upgraded.

Being at Microsoft has its own benefits

I owned an important piece of project in Microsoft. There was a talk going on to fasten the velocity of work we were doing. Given the complexity of the project, its architecture was written in many layers few of which was coded by team at Redmond. Due to time zone difference and the critical timing, we had to act on it quickly to enhance quality of product. They decided to send me over to interact with people, understand different layers and their communication.

A sudden plan

I hardly remember traveling somewhere in such a big rush. It was 4 O’ clock in the evening when I was checking flight tickets and changing date in the calendar on the online portal to finalize which day to travel. 6 O’ clock, my friends found a flight that was to take off the next morning to Seattle and I spent next hour mentally preparing myself to fly so unprepared. It was just hard to believe that I would be traveling to US, one of my dream destinations without any preparation. My parents were asking me every other day if I bought winter apparels. I usually prefer to plan everything in advance and this time, without have a flight ticket in hand, I didn’t want. With support from my friends at Microsoft, I finally decided to give it a chance. There are few things in world for which you need not to be prepared. After all, traveling somewhere without much thinking has its own share of fun. And this was not somewhere. This was what I dreamed of long enough.

It all started with a joke. I was worried I was not getting any ticket in good airlines next week. I was tired, exhausted not a clue on what to do. “There is a flight next day at 4 in the morning. You can catch that.”

“Holy cow! This would be too early. How on earth would I be able to catch that?”

I knew they were serious when my manager said. “Actually, I think you can go.”

“But I haven’t done any shopping”, my forehead was shining with worry lines.

“It’s alright. What are the things you need? You can borrow them from me.”
My friends helped to prepare an itinerary. I literally got only 2 hours to dine and pack my bags. I usually never take more than 30 minutes to pack, but since this was my first trip to US, I didn’t want to take any chances.

It’s Emirates, baby

The moment I stepped into the flight, I got the answer why it has been coined as the best airlines in the world. The service, the infra and the experience was just amazing. It is very unlikely that you would be left unhappy after an Emirates travel. It was a 22 hours long journey with a 3 hours layover in Dubai. Being a movie buff and their huge collection of movies, I didn’t find it difficult to spend time.

Hello from Redmond!

The flight was just on time. You might find it funny but the first thing I missed at Seattle airport was no taxi driver asking me where would I want to go. I didn’t have US Sim Card and it was freezing cold to stay for long in the open weather. There are two Marriott hotels in Redmond and I missed to mention which one I wanted to go to the local taxi. Even with a 50% chance of landing at the correct hotel didn’t work for me. Redmond is kinda a developed village. It’s hard to find anyone on the road. It was near difficult to ask someone for navigation. Luckily, the second Marriott was just a few blocks away.

Few of the pictures of the hotel:

16114143_1402536173099520_2625156290256392395_n1

I learned that labor is costly in US. The gorgeous lady at the business center handed me over a map which had directions to follow my room. It’s very unlike in India that you would have to carry luggage to your room on your own in a decent hotel.

My first status update from Facebook on the arrival night.

It’s been only 11:00 PM here and I am done with sleep. It’s quite chilly outside and the roads are empty. A grave silence is there in the winds. Next couple of nights, I am gonna spend as a night crawler. I wonder if the new government would encourage vigilante. All of a sudden, I feel like I have all the time in the world and I have very less to do.
If I was not able to respond to your chats due to my busy schedule, Let’s catch up now

Being a hobby photographer, I found everything very interesting and screaming at me to be clicked.

The view outside my hotel room. As you can see, cars are parked in the open air. In the morning, the car windows are covered with a thick layer of ice.

Just by the first look, I can say that discipline and patience flow in veins here. I never saw anyone rushing, everyone (well almost) greets you with a wide smile, cute children laughing on pavements and the most important thing – punctuality. People prefer to be on time. They dine by 8, sleep by 11 and woke up at 6.

Good morning Redmond

It is said that breakfast is the most important meal of the day. You don’t realize it until you skip dinner and have a heavy breakfast in Indian style dinner. Good morning Redmond!

!JetLag

I was under impression that I won’t be getting sleep at usual time because of all the jet lag stories I heard. To my surprise, jet lag did magic to my schedule which I couldn’t follow even after trying for 10 years and many apps claiming to help you do so. I slept at 10, wake up at 6 and rushed to office by 8. It was just an amazing feeling. It was refreshing. I was way more productive. I never knew a good schedule can do miracles in your day to day life.

This post was residing in my draft for quite long. I finally got some time out of my busy schedule to refine it.

The first question quickly pops up on why am I writing this post at all. There are already tens of hundreds of similar compilations on web that talks about this.

Well, following reasons compelled me to do so:

  1. Being a GFG moderator, I’ve been getting many requests from readers through various social media (FB, LinkedIn, Quora, InstaGuide) and various mail clients asking for mentorship and guidance on how to prepare for top MNCs like Microsoft, Amazon, Google etc
  2. Having gone through similar journey and witnessing many of my friends succeeding, I feel knowledge should be shared. My experience might be useful for newer generations who happen to chase the same goal as once was mine

Please note that this article is purely a reflection of my learnings, what I followed through the years and my experience. This is NOT the only way to improvise on what is needed – your coding skills, strengthening DS & Algorithms and boosting problem solving skills. I repeat, this is NOT the only way. There are things I couldn’t follow because of time constraints or didn’t follow because I was just not aware. Please comment if I missed anything which is worth mentioning here.

Language

Language has been a topic of debate between aspirants since years. It’s always good to master one language, knowing ins and out of it rather than hopping from one language to other. Why?  Because sometimes it might happen to you that when you get a problem, you start wondering what language you should choose and your focus is compromised. When you should really concentrate on problem solving, Implementation comes later. Then while you are coding, you plan to change the language in between. This won’t serve you good in interviews. If you’re able to solve a problem in language ‘X’, eventually you will also solve it in language ‘Y’. Learning a new language is just a matter of time. A language might not be as widely used after 5 years as it is being used now. Your ability to solve a problem will what matter in the long run.

I usually switch between C and C++. If time is at its crunch, I prefer to use STL (standard library functions) instead of writing my own version of Linked List. If I want to develop a project, an android app for instance, I go for a managed language because it is easier. If I want to automate something to save my time, like replying and liking my birthday wishes, a python script is the saving grace. You got the point, right? Master one language and learn others as per requirements.

Data Structures and Algorithms

Data Structures and Algorithms is very important and serves as the backbone of problem solving.

For beginners, Fundamentals of Data Structures in C by Sahni Horowitz is good. After reading it, you should be able to understand basic Data Structures, how they are implemented and fewer examples where they can be used. Don’t expect to learn advanced DS through this. After your basic concepts are clear and you are comfortable implementing them in a language of your choice, you can work on learning algorithms and solving problems.

Many sites (including GeeksforGeeks) present problems in a very adhoc manner with no order of difficulty level. This makes things difficult for beginners because they don’t know the difficulty level of the problem they are attempting. Data Structures and Algorithms made easy by Narasimha Karumanchi is a good read after you are comfortable with the basics. It has pretty good collection of problems organized by difficulty level. Just make sure to try to solve problems on your own instead of rushing for the solution. Once you have a fair understanding of DS and have got some confidence in solving problems, jump to online portals and start solving problems from topic of your choice. GeeksforGeeks is good to start with.

For Algorithms, Introduction to Algorithms by Cormen is a must read.

Advanced Data Structures

Sometimes, basic DS don’t serve the purpose to solve problems and you need to know advanced DS. Day to day problems like implementing a prefix based search for a phone contact list to finding the dictionary word from a jumbled sequence of characters need special kind of DS. There are many of them – TST, Trie, Suffix tree, Suffix array, Fibonacci heap, Segment tree, Gap buffer, Rope, Skip list, K Dimensional tree and so on. While it is good to know the implementation of these DS, I would suggest to also know when to use one.

Problem solving

So you got a gun, understand how to use it, probably have used it before. If you are going to fight a war, you won’t like to rely upon your amateur experience. You would prefer to practice hard to save your ass. Now try to think it in perspective of problem solving. You know what DS are. But you also need to know when to use one. Welcome to the world of problem solving. You are given a problem and you are asked to solve it. That problem can be anything starting from a simple puzzle to implementing a user scenario. You must have noticed degree of connection feature in LinkedIn. How will you implement it? Does your approach take care of scalability? Will your code crumble when user base increases ten folds? This is the most important skill top MNCs usually look for. How do you approach a problem? How do  you divide it into modules? How do you solve each of them and then combine them?

Dynamic Programming

I separated out DP because it is one monster which is difficult to master upon. No matter how many problems did you solve in the past, a new DP problem can always surprise you. The more you will practice, higher the chances will be to find out patterns. Google is peculiar about DP. You should expect at least one DP problem per interview round  if you are preparing for Google. Practice DP section from:

Competitive Programming

Competitive Programming plays a very important role in boosting problem solving skills and ability to perform under time pressure. Do participate in various online portals like TopCoder, CodeChef, SPOJ. Here is a post on Getting started in sport of programming.

Design and testing

So you are good in DS and Algos. You are probably good in problem solving as well and you come up with different approaches with varying time and space complexity. The problem which you solve in Competitive Programming is well defined and has to work under an environment which nobody will probably use. What if you are asked to implement a user scenario. The problem statement is usually vague and you need to discuss a lot to resolve ambiguities. This is where design comes into picture. How will you design a redo-undo feature? What data structures will you use to store history in a web browser? How will you implement auto-complete feature in address bar? Let’s say Amazon wants to build a feature that would resume a video stored in cloud from any device. What data structures will you use? How will you scale up things? Does your design take care of concurrency issues? What about the performance? What if you and your girlfriend share the same cloud account and are trying to play the same video from different devices?

Now you have thought through the design well, have come up with different data structures to use with pros and cons in mind. While implementing, you must take care of corner cases. You must be aware about the integer overflow issue in Youtube video view count. While implementing, they never really thought that the view count can exceed what an integer variable can hold and BOOM, the view count cycled back to zero.

Before a feature goes live, it must be tested well. It is good to practice some test questions as well. How will you test a Insert image feature in MS Word? What about a cut-copy-paste feature? How will you test Temple Run game? Try to write all the possible test cases and how you are going to handle this in your code. Writing a robust code is very important. If you take care of these things at an earlier stage, you can avoid silly bugs (and boost your chances of getting selected in interviews).

What else?

Have a sound understanding of Operating System. The dinosaur book by Galvin is a good read. Know how networking works and have insights on DBMS.

Resume building

First impression is the best. Resume is the first thing that HR will use to decide whether to call you for interview or not. And they have got hundreds of them. So they will usually scan it for 20 seconds to 2 minutes. It should be clean, concise and elegant. Each word mentioned should worth the space it eats. The rule of thumb is if you have less than one year of experience, the size of resume should not exceed a page (with few exceptions).

Few points to note:

  • Maintain a header to fit info like name, email id, address and contact number
  • Mention level of expertise corresponding to each language. Example: Proficient in C and good at Java
  • If you are mentioning a project, write your key learning, impact in the team and . If this project is online (an app), don’t forget to include the link. This will show that you built something that is being used by people . Guess what, this is what companies do, building a product, stabilizing it as per user feedback, taking in new feature requests and so on.

Here are few useful tips from Gayle – What are common mistakes that applicants make when writing their resumes for tech companies?

How to apply for Microsoft?

I get many messages asking me for a favour to refer them. When I ask them how much comfortable they are with DS and Algos, they say good enough. Then I rephrase my question to how do they feel when they solve interview experiences at GeeksforGeeks. Either they haven’t heard of GeeksforGeeks or they never read. This is not a surprise. GeeksforGeeks is still growing. But when I ask them a problem on DS by tweaking already existing famous ones, all they say is they haven’t solved this problem before. Please do NOT do that. It’s one thing to yearn for something. But quite other to put efforts to make it a reality.

If you are not able to clear the interviews, you will have wait again for 6-12 months depending on the company policy before you can apply again. Now coming to the point,  you can apply for a position at Microsoft either through Careers page or through referral. Referral usually bumps chances of getting an interview call because your resume gets to the system through a person Microsoft trusts to be a good engineer. How do you ask for a referral? It’s simple. Forward your resume to someone you know working there. No one will say NO unless your resume is filled with something which doesn’t fit company requirements. Rule of thumb is we believe in solving problems and if you are good at it, we would love to see you here. Remember, everyone wants to work with a smart person. And this is usually true for any company, not just for Microsoft.

Do’s and Don’ts

  • Practice, practice and practice
  • Make a habit of writing clean and readable code (avoid variables names like i, j)
  • Make sure to handle all corner cases
  • Use pen and paper to practice code. In interviews you have NO access to a compiler
  • Don’t mug up the solutions. Try to solve on your own
  • Think of different ways of solving a problem and thoughts on why one should be preferred over the other

Resources

I have answered few questions related to interview preparation on Quora. You might find some content missing here in blog and it is intentional to avoid the duplication of efforts. Please read my technical answers here.

Resources (which I haven’t talked about):

  • Cracking the coding interview by Gayle Laakmann: A must read once before interviews. It covers aspects like what interviewers expect from you, how to deal with behavioral questions and few interesting problems. It will change your thoughts about design and test problems for good
  • GeeksforGeeks: A bible of problems (with well explained solutions). Make sure you do NOT rush for solutions. Try to solve problems on your own no matter how much time does it take. With time and honest practice, you should get better
  • CareerCup: A huge collection of problems. Though you can’t rely upon solutions, it provides a rich community for discussing problems. I found it good for discussing design problems
  • Project Euler: A heaven for mathematics lovers. You solve the problems using some formulas on paper and then write code to get the final solution. Solve at least 40 problems from this site.

Ever since I penned my journey, the response has been quite positive. It seems like a 3 days extended weekend which I was thinking a waste wasn’t a waste at all.

There were countless moments of mood swing. I already had an offer from Microsoft. I wondered if I should try for other biggies like Facebook or Google. Bottom-line was, I had fallen into procrastination trap. I was shy of 9 months to join Microsoft. I wanted to enjoy life. I wanted to take a break. My then friends at Google and Facebook had mixed suggestions.

“Dude, you should really give FB a try. I can refer you and interview would be scheduled in 2 weeks”.

“It’s time to explore. Once college is over, you are never gonna get it. This is the time to have some fun”.

Out of those precious 9 months, I spent 5 months at home doing almost nothing. Major chunk of my time was invested in only eating and chatting. When boredom seemed to kill me, I just used to compile an article on GeeksforGeeks. It was fun.

Sometimes even a simple mail gives you goosebumps. I had a message from Google recruiter mentioning my profile looked interesting and  if my interest was aligned, they could commence the interview process. With the mail was attached a video covering their expectations from a candidate in Google. I thought of giving a try to Google. But my practice was at a slower pace. Writing articles and solving problems were just to kill time and pure altruistic. Google is a big brand. I definitely wanted to try my luck there. It was just not the right time. It would be a pleasure to enjoy Microsoft etiquette for the time being.

The next phase begins

A long rest had finally come to an end. Nothing could make me happier than to see a person waiting at the airport holding a placard with my name imprinted on it. He directly drove us to Rejenta One. A month stay in a 5 star hotel, dedicated car, a driver, couple of good friends and new city. Whole world around me was screaming to explore it.

Life at Microsoft in a nutshell

Life of a Microsoft Engineer

 

GeeksforGeeks after Microsoft

I usually get messages like, Why my contribution to GFG has slowed down. Is it because of my busy schedule?
Seriously speaking, the passion which was ballooned inside me 3 years ago has faded. Coding is not the only thing that fuels me. In my college days, I used to code for fun. Whenever I found myself struck by the boredom lightning, solving a new problem or brainstorming a better solution was the saving grace. My contribution has been greatly compromised and now if I write, my focus is more on the quality rather than quantity. I must say, I am a slow writer.
Sometimes I ask myself, what do I know except coding? Is my life all about staring at the screen and writing geeky characters? A lot of things are there in the world and you won’t know what you would like the best until you give it a try. Life is made up of series of moments. It’s not the number of years we live that matters.

For the past few years, I had been wondering what my life is meant to be, what are the things out there which will render me with greatest pleasure, what is the secret ingredient of being happy.

The other side of my life which eats most of my time when I am not in office writing and debugging code, is as farthest from the geeky profile as it can be. This is a long story. And if you’ve got some free time, read What profession would I have chosen if each profession is equally valued and earns me equal salary?  on a boring day while sipping a cup of coffee. I am sure you would like it.

Geek on the top

A usual week day, a mail popped up asking for my interview. It’s really weird if someone asks questions about you and your life which is going to be published on a broad scale.

The interview is published here – Geek on the top – Aashish Barnwal | Make a habit of writing clean, readable, flexible and robust code

I am still learning. I am still exploring. It’s always fun to try out new things and most importantly, we must find happiness in whatever we do.

In the last part, we read the story of a boy who wanted to live his dream no matter what the cost. We will resume from the moment Microsoft campus visit was announced.

Success

When your friends are celebrating hard, throwing parties, while you try to avoid them and lock yourself instead, questions like this are obvious.
“Which is your favorite company?”, my friend asked.
“You’ll know soon”, I murmured.

It is difficult if you are in a non-enthusiastic environment where people around you are even scared of dreaming big and setting higher goals. In case you speak loud your aspirations, they try to pull your legs. There was no space for mistakes. Opportunities knock rare often and fortunately I knew it. I was gonna get only one chance. That’s it. If I miss it, I miss it. This could be a regret I would have to live with. Other good companies in line offered half the money Microsoft did, leave aside brand value, perks and work culture.

Microsoft express

The time had arrived. It was the same day and time Hogwarts Express leaves from Platform 9¾, 1st September, 11:00 AM sharp. If I wanted to board the train, I had to cross the barrier first. And that barrier was written tests. The train would then test your patience, perseverance, hard work, skills in its journey. If you failed in between, you had to board down. If you passed, it would directly lead you to Microsoft. Like Harry, I too didn’t wish to miss it.

Hogwarts

It all began

It was a hectic morning. There was a big rush in washrooms and people were running around. The first written test was pretty easy. 15 objective questions and 30 minutes of time. 77 out of 400 made it. The second written test was scheduled the very next day.

I and Abhinav were sitting next to each other, barely talking to anyone. We had to code 3 problems in 60 minutes on a text editor leaving any scope of compiler correction. You know it went well when you wear a smile after you finish. Luckily, We were able to solve all problems.

Rumors were in the air. Microsoft usually takes time to evaluate the written coding round. We were not sure when the result would be announced. Honestly I wished it to be soon. The sooner, the better.

The quiet before the storm

I was gravely quiet most of the times. May be because I was thinking about the problems, and about the interviews, and about the list of things to do if I get selected. Millions of things were itching in my head.
Solving interview experiences was kind of comforting. “If this is what Microsoft asks, we should do well”, Abhinav and I always said things like this.

Year 2012, September 16

Boarding Microsoft express

I have never been an early bird. Still I managed to wake up at the crack of dawn. We gathered in the auditorium at the first blush of the day. Result of the written was announced. They shortlisted 30 out of 77.

Microsoft Interview

Four years it’s been, and yet, here I write as if it were only yesterday. I remember every small detail, every word I spoke and each discussion I had in interviews. Either my memory is not that fragile or that was quite a big day for me. I still don’t know the answer.

I hadn’t eaten anything since the morning. The spirit was keeping me up. One group interview followed by two rounds of face to face interview each lasting 60-90 minutes and fear of losing it anytime as if a sharp edged sword was hanging across my head was enough for one day. They kept on rejecting candidates as each round progressed. The number trimmed from 30 to 14 to 10 to 5.
In the third round of interview, he said I had already proved I was a great coder and he wanted to check how I perform in other areas like design and testing. I was also asked to showcase my passion for technology. We discussed about various products, their design, why they were designed that way and why I liked them. It was fun discussing the technology (Gap Buffer DS) used in Text Editors, automata and compiler. I can understand his love for these as he was working in Visual Studio team at Microsoft. He then moved on to discussing things like which role I wanted and why so. He saw same passion in me that he observed in one of his friends and he was doing really great at Microsoft. This was the longest round and lasted around 90 minutes.

That night, when I was in cafeteria to catch sandwich, I stumbled upon a guy. He asked me how would I like to be beaten. Funny part was, we had hardly talked in 3 years of college. The same day I got few congratulation mails, although 2 more rounds of interviews were scheduled on the next day. I was very close but I was still one step short of milestone.

Day dreaming

I remember those silly thoughts that popped up our minds. When we’ll make it, we would have two refrigerators in our house. One for food and other for drinks. When we’ll make it…. The food in college hostel was horrible. If you had Veg Manchurian once, you would put all efforts to stay away from food like that your whole life.

Two more rounds of battle

When your name starts with 2 A’s, you are always the first one to face everything that calls for first name protocol. I suffered it my entire college life. I wasn’t spared in Microsoft interviews either. Each round of interview started with me. Abhinav was the last. Those in-between were trimmed down.
I was just on time for remaining two rounds when they surprised me to know that my one round of interview was cancelled and I had to face last round with hiring manager on Skype. Unlike an HR round, it was purely technical focusing on design, testing, Big data, Graph and Social Networks. We discussed many things few of which I had already covered in GeeksforGeeks posts. Thanks to Facebook for writing technical details of architecture they use which I was lucky to read. It lasted around 90 minutes.

My interview experience at Microsoft

Restless nights

Time seems to freeze when you’re waiting for it all along. Nights were restless. Days were better neither. Mood swings were at its peak. Right from the day Interviews were over, everyone I stumbled upon asked the same question, “Hey! When the result is coming?” or chirped comfy words like, “I know you’ll make it”. It was eerie and I just didn’t know how to react.

Year 2012, September 24

The BIG day

It was an Intel day. Although I wasn’t interested, I suited myself up to check what they had for me on the plate. People were getting called for interviews and I was waiting for my turn reluctantly. I was just hoping for a magic, to know the results of Microsoft interview. This could push me to do fair in Intel.
And then, I heard my name. “Aashish and Abhinav! Are you there? Please come on the stage”. I wasn’t sure what had just happened. Abhinav was sleeping in his room. He wasn’t even there. Every pair of eyes was staring at me as if I was being X-rayed.
“Congratulation! You have made it. They have just mailed us the result.”
“Microsoft has selected Aashish and Abhinav”, they boomed on microphone after a pregnant pause.
The auditorium burst in cheers and claps. Oh Buoy! That was the moment. I was feeling like a celebrity. Everyone was shaking hand and congratulating. I was on cloud nine.
All I wanted was to run away to tell my parents that they could finally be proud of me, to tell Abhinav that we had done it.

People were running after us. This is a tradition. They beat you with belts on happy occasions. Happier the moment, harder you’re beaten up. You can hide buried treasure or a winning poker hand. But you can’t hide the true happiness. It was all around. Between shaking dad’s voice soaked half in tears & half in happiness and mine out of control flowing emotions, I was feeling no pain.

I was bombarded with messages, mails and calls. For once in my life, I wanted to be alone. It was my time. I wanted to live it. I wished to freeze it. I wished to hold it. Christmas had arrived little early for me and Santa had bestowed on me. It was the best birthday gift I could imagine. It was a magic. They say, all magic comes with a price. And I think I had paid the price.

Rumple

There were few awkward moments when Abhinav and I overheard things like, “Look, 32 lacs are going”, while we were wandering on college roads.

Year 2012, November

We were in news

It had been almost two months since result was announced. I was on a long vacation, sleeping at home when I got a call from placement department. They wanted a picture of me to feature on the site. Few days later, my cousin brother called me to tell that he was holding college prospectus featuring picture of me.

College

The diabetic sweet deal

There is nothing much to do after interviews. Scoring GPA in college was least of my interest. I wanted to learn something which could smoothen my path in company but my friends on Quora advised me not to bother. Most of my time was spent in eating, sleeping, chatting and GeeksforGeeks. I was having a word with one of my friend when he asked me if I was going to join Microsoft or GeeksforGeeks.
As usual, Sandeep and I were discussing about GeeksforGeeks, plans for its growth, revenue model etc. He asked me my thoughts about career. “Seriously, the way GeeksforGeeks is going, you might like to join full time. You can choose designation of your choice – CEO or CTO”, he proposed. This was overwhelming, a very sweet deal indeed. Sandeep’s offer was very difficult to reject. However, a lot of things were on stake. GeeksforGeeks was in very early phase. Working in it full time would render me literally poor. Microsoft was a brand even my grandfather talked about. It was really a tough choice to make. I decided to spend few years at Microsoft to learn things, to learn how stuffs work, to learn something industrial. Microsoft was changing tens of millions of lives and I wanted to be part of it.

Godfather

If you ask me, whether I regret my decision today. Well, I ain’t sure. Life is made up of small moments and each moment has its own pros and cons. A choice doesn’t come with a warning sign. Sometimes, you don’t know what is going to happen. Sometimes, you don’t wanna care. Sometimes, all you wish is to live the moment. Today when I have nothing to do or when I am really pissed off at work, I think of that time. I get lost in a reverie imagining how my life would have been changed. But thinking about it won’t change a single dime of my life. Even if I join GeeksforGeeks today, it won’t be the same it was 4 years ago.

What do I feel when I look back today?

Decisions you make lead to doom or fame
I guess there is no one to blame
Sometimes you rise, sometimes you fail
But things you learn are worth a hell

There is no secret ingredient. Healthy dose of faith. Genuine commitment. Sharp focus. Hard work. Everything should be put in right proportion. I didn’t do anything different. I believed in myself and followed my passion. My life has been a roller coaster and I enjoyed the ride thoroughly. You make mistakes and you learn from them. It is part of life.

Kung fu panda

GeeksQuiz

Our goal at GeeksforGeeks was to maintain quality content. Few of the readers asked for content to focus on basics. That’s how GeeksQuiz idea was born. It was Sandeep’s brainchild. I wasn’t interested much in site development. I chose to contribute to content instead.

The most awaited offer letter

I don’t know why most of the comms Microsoft did, happened to be in the early morning. The HR inboxed me the most anticipated offer letter. Three days after we received offer letter, they shot another mail inviting us to an event “New Hire’s Day”. It was exhilarating and hell lot of fun. I have documented my experience here: My experience of New Hires’s Day at Microsoft

Year 2013, Summer

What can be more difficult than solving a problem? Well, creating a problem. IIIT-Bhubaneswar had a tech fest in summer. They asked GeeksforGeeks to organize the coding contest. Designing problems was very challenging. I had never thought from the perspective of being on the other side of the table. There were many things to be taken care. Problem should be new. Domain of problems should be proportionally distributed in different difficulty levels. But how do you decide the difficulty level? If you’re the problem setter, you happen to know the solution. Does that mean the problem would be that trivial for others as well? Have you ever wondered how they categorize difficulty level of Sudoku? I will leave you keep thinking. It was a different experience altogether.
They had also asked for a guest lecture in the college. Since I was in the town, Sandeep asked me if I wanted to go. Sadly, I was not a good public speaker. One of my part wanted to go, but the other was pulling me back due to my fear of stage. Unfortunately, my other part won the battle and I ended up watching Batman.
