Amazon Software Development Engineer interview questions

I was contacted via phone by an Amazon recruiter, who scheduled a phone interview the following week. This interview was then rescheduled for the following Monday due to a last-minute meeting that my interviewer had to make. The recruiter was very pleasant and helpful. The interview went fairly smoothly - two 45-minute sessions with different developers for a total of 90 minutes. It was very technical, but the interviewers were very patient and understanding - I got the feeling they wanted me to do well.
