Amazon Software Engineer interview questions

I was first contacted by recruiter and explained the position. I did first phone screen and i was asked data structure questions and immediately got second phone screen. I was asked OOD question in 2nd phone screen and invited 1:1 interview afterward. There were 6 1:1 interview and it was little bit hard. I did good but not good enough to get the offer :)

I had 2 phone screens, which were quite pleasant. In both they asked a few general programming knowledge questions, then a "write some code". The code was simple, atoi() function and tree ordering. Each phone screen was very laid back, took about an hour. The physical interview was grueling. Not necessarily the questions, they were fairly standard programming questions, but the length of the interview. I was assigned to interview with 2 teams at once so I was there for 7.5 hours all totaled.
