Microsoft Software Development Engineer interview questions

It took about 1 week for them to give me an interview. Applied through the school recruitng system. Since it's a first round interview, the coding is not so hard but I just can't remember through.

Got in contact through campus recruiting, then had a 30 minutes on-campus interview. The interviewer was very rude when I couldn't code up the algorithm in time, he just said "Times up. It was nice meeting you. Bye". Though I was five minutes late to the interview and the interviewer was not happy about that, it was still an unpleasant experience. I tried talking through my code when I got stuck, and the interviewer mostly just ignored me and typed on his computer.
