Amazon Software Engineer I interview questions

passed the first round on campus, will take 3 more one next day

Had a on campus interview and they asked a lot of technical questions. They asked about sorting algorithms as well as about dynamic programming. The interview was very intimating as the interviewer was on his laptop the whole time and didn't speak to me much. They just sat on their laptop and gave me a problem, then kept asking if I was done every 2 minutes.
