I had an on-campus interview at my University, where the interviewer focused on design issues and basic algorithmic questions. I can remember couple of questions - how to determine if two circles intersect and how should a server behave if it has to crash (maybe gracefully) and come back up. On-site interview was scheduled after a month's wait, and I had to schedule it for the next month since they had no slots. December-Jan is the holiday season, I guess! On-site interview was 5 rounds. First two involved coding and then coming up with as many test cases as I could for that code, to achieve maximum coverage. 3rd was the lunch interview with test lead and very casual - mostly just chatting about the interviewer's experience with Microsoft so far, and many questions on my projects and internship. Fourth one with a test lead was tougher - totally testing oriented where I had to fix a piece of code he wrote on the board, and then many test cases for that piece of code. Also a very interesting question on how to test a map where he gave me an upside down map and we had a discussion on whether it was valid (it was an Australian classroom map, and valid.) Fifth interviewer was the test manager, and we had a great time classifying test cases for testing the find function on notepad. At the end he told me I had the job - I had requested an expedited answer since I had another offer pending.
