Microsoft Program Manager interview questions

I was there for a hiring event. They flew me out to seattle and covered all my expenses. I had interviewed with them a year before (I did not get the position then) and they just called me back for final rounds. The interviews started at 8 am. There were many other applicants there and we were all applying for positions in the Office Division. Everyone went through a series of 4 interviews back to back. Each interview was 1 hour long. The interviews were over by noon. I got my results the same day.
