Microsoft Software Development Engineer interview questions

Applied through Campus career fair, got email from HR to schedule on campus interview in a few weeks, first round interview on campus/I had a fair negative experience interviewing at Microsoft, the first time the interviewer didn't show up and missed all the candidate interviews in the morning ( There were about 8 of us) and the second time since I got another offer I emailed the HR asking if I could get my feedback from the interview and they simply informed me that there was no record of my interview feedback. This is pretty disappointing and I don't think it leaves me a very good impression about Microsoft.
