Microsoft Software Development Engineer interview questions

The onsite interview started at 8am. They had a hotel at the shuttle to pick a group of us up at 7. You will be interviewing for the same position with a group of other people, though the actual interview portions are 1 on 1. It's 4 interviews and then lunch. They questions alternated between the interviewer seeming to think I was completely incompetent basic programming questions and normal fairly difficult technical interview questions. There is a good amount of emphasis on your past experience, and a decent amount of the harder problems only required pseudocode. It is 8am, and there are only minimal breaks between interviews, during which you sit in the lobby chatting with your fellow interviewees/competition. There's some food there, as well as coffee, but be prepared to not have much time to eat or mentally refresh between interviews.

A screening interview first then the on-site interview with 3 developers. Interviewers were not really helpful and I couldn't understand their real questions. It would be nice if they have given some food since I was there for 5 hours and eventually I got hungry. It would also be nice if they have given the feedback from the interviewers.
