I had one on-campus interview and was then flown to Redmond for on-site interviews.

I was never informed which team would be interviewing me. On the day of the interview, I finally found out it was the User Experience group. I was a purely systems guy with two years of experience in Linux Kernel programming and was obviously expecting an interview with a core OS group.

They conducted three rounds of interviews, which frankly speaking went quite well. I received no feedback as to why I was rejected.
