    Interview Details

    I interviewed through college recruiting. First round interview was really easy, he just asked me to implement a queue and test it for certain conditions. Then I flew to Seattle for the final round where I had to go through 4 back to back interviews. The interviews were mostly technical, but 4 hours of technical interview really gets to your nerves.

    Interview Details

    The recruiting team does a great job, they are very helpful and always willing to help. On the day of your interview take full advantage of your recruiters by asking about the company, background of engineers working there and what they expect out of their potential hires, although you may know a lot about the company from online sources, I would recommend asking the recruiters these questions as you will get a clear idea.

    Focus on a lot of functional test cases first especially when they ask you to test the code you write, dont worry about where it is used and which application makes use of this code as you may waste time in clarifying and get lost in thoughts, as the interviewer would say, I just need functional test cases.

    But remeber when they ask you to test a application or some real world about then think in a methodical fashion like Test environment, Use Cases, Functional Tests, Special Test cases like Globalization tests, integration etc.

    Make sure you understand the question. Some times they may not give all the details in the question they ask, they want to see how you get the most information out of them. Dont proceed without understanding the question! and also make confirm whether you are allowed to use additional data structures or helper functions.

    You may have read that you have to think aloud when you write a program, if it works for you great follow that. For some people like me, I usually get lost in thoughts if I do that, so what I did was I told the interviewer I will take 5 mins to analyse the problem and come up with the solution and I will explain it step by step. If you get stuck just dont stare at the board, tell the interviewer your logic and where you are getting stuck, as they may give you hints which are very helpful.

    First round is usually is easy, they want you to get comfortable, so dont ignore programs like fibonacci, common factor, which are very basic problems. As the rounds progresses it becomes harder.Your energy levels and the thinking speed drops as you cruise through the day. Make sure you have practice working on problems for long time period(). For this just like a week before, try to setup a mock interviews with yours friends stretched out for a day packed with five 45 minutes interview with 15 min break or if your friends are busy ask your friend to randomly pick problems write them into a piece of paper and place them into 5 different files. Try to work on them the whole day. Trust me this will definitely help you. On the day before the interview please please relax and get a lot of sleep dont try to read something you dont know cause it messes up things which you know and drops your confidence levels.

    Focus on String manipulation, Lists, Tree traversals, very very important topics for a microsoft interview. Learn from the mistakes other people did, trust me it will make you better a programmer. Good Luck fellow programmers!!!!
