Submitted resume through my university and got invited to interview on-campus two weeks later. The person in the career fair was very nice and helpful. One day before the interview, the two persons from Microsoft held an event for all the candidates. Very few questions were asked by the candidates as the two interviewers spent a lot of time talking about the company. The day of the interview, the interviewer was nice for about 2 minutes. After that, he started behaving very disinterested and spent more time looking at his laptop screen than listening to what I had to say. His behavior made me very nervous, and plenty of times he interrupted to give me hints that I didn't need. Any pause for a few seconds would result in a comment along the lines of "You aren't doing what I asked." Two weeks after the interview I received an e-mail to tell me I didn't make it to the 2nd round. My overall impression is that unless you can code recursive algorithms in less than five minutes, you shouldn't apply at Microsoft. Also to potential candidates don't forget to prepare for behavioral questions.
