Amazon Software Developer interview questions

I applied in the Amazon website for Software Engineer position. One month later, I was contacted by email and requested to do an online test. Basically it had 3 question, two theoretical question and one programming questions. You could choose your preferred language. The exercise was medium difficulty, and should be completed in ninety minutes. If the program didn't compile you will not take in consideration for next round.

I went though two telephone screens/interviews before being flown to Seattle for a day of interviews on site. The telephone interviews were typical computer science interview questions - mostly around data structures and file systems. The on site interview was 5 part with 5 different people for about an hour a piece starting at 11am and going through the afternoon. Multiple interviewers were former Microsoft employees and spent a significant amount of time talking about what they left behind at Microsoft. One interviewer was very confrontational. I followed through with the day but a couple of hours in I decided I had no desire to work for Amazon.
