I had dropped my resume at the university career fair and got a call for an on-campus interview a couple of weeks later. It was an easy one with one technical question (Perform a level-wise traversal in a binary tree) and a few HR questions. Another couple of weeks later I got a call for the on-site interview for SDET position. I have to say Microsoft really pampers the candidates and gives a very good first impression. I was flown to Redmond and put up in Westin. Limos were arranged to pick me up from the airport to hotel and from hotel to/from Microsoft campus. It was a day long affair with 4 back to back interviews and the recruiters made sure that the time between the interviews was relaxing and helped a great deal to reduce the stress of an interview. Interview 1 A small coding problem which wasn't really difficult. I was then asked to test a parking garage. Make sure that you cover all possible scenarios and test cases. I was pretty satisfied at the end of this interview. Interview 2 This was a young enthusiastic guy but it turned out to be the worst interview for me of the day. We started with test cases for some function, and it went pretty well. Then he asked me to come up with a method to find anagrams in a dictionary and then kept making the requirements and scenario more complex after each proposed solution. I came very close to the optimal solution, but even then I felt I took too much time in doing so. His feedback was that I should be asking more for the problem details instead of concentrating directly on solving it. It was a good point to remember but at the end of the interview I felt I could have done way way better and was a bit disappointed. Interview 3 This interview in fact began while we were walking from the conference room to the interviewer's office. We talked about my interests, why Microsoft etc etc. And then came the most stressful part. He asked me how I would test a toaster that is supposed to toast bread in outer space. Interesting problem, and thanks to the feedback from the 2nd interview I spent a great deal of time clarifying the conditions in which it would be used, who will use it etc etc. I must have come up with at least around 30-40 cases, but he kept staring at me as if I was missing out something obvious. I guess he wanted to test if I could think under pressure. This went on for about 20-30 minutes. We ended up with a small coding exercise and I was happy with my performance. Interview 4 I was quite tired by this time and I think it showed. The interviewer had been there for 13 years and he was very comforting. He then asked me to test a particular function. We went over many test cases and once we were done, he told me to write the code for it. This was fun because I had to ensure that my code passes all the test cases that I have come up with myself. He helped me a bit along the way and it went smoothly. We, the candidates were then taken for lunch and then were free to roam around the campus. Happened to see Steve Balmer too (he was busy on his phone). I returned back to the hotel and slept the whole evening. My flight was the next day morning and they had given me taxi voucher's to cover the fare. Got the offer the following week. I was a bit apprehensive since I felt my 2nd interview may screw up my chances, but I guess it did not. I accepted it and now I am totally looking forward to joining them.
