Microsoft

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.
