Amazon Software Engineer interview questions

There were questions about stacks, sorting large datasets, database organization and more over the course of two phone interviews. I had a hard time getting any info about what position I was actually interviewing for and what the team did. I mentioned a few times that I didn't want to work in Java full time, but nobody would say if that was the case, and I think that may have been a problem in getting past the second phone interview.

Their interview process consists of two phone interviews and an in-house interview that consists of 4-7 45 minute-1 hour interviews. For my first phone interview, the interviewer was very friendly and prompt. He called on time, explained the process and got right into the questions. For my 2nd phone interview, the guy calling me was a last minute replacement, and it showed. He was about 10 minutes late to call, sounded like he wasn't prepared and generally didn't care about the interview. I was lucky that I made it past that call... Both interviewers allowed me to ask questions for about 5 or 10 minutes after the technical questions they had. The in house interview began at 11 and lasted until about 4:30, shorter than I was expecting. Everyone was very friendly and I really didn't feel intimidated at all. It went very well, but I didn't receive an offer. The biggest downside to Amazon's interview process is that they don't give you feedback on why you don't receive an offer. I thought I had a very good interview, but didn't get an offer. From what I have heard, they have a 1-2 year span after "failing" an interview that you cannot apply again to Amazon, but I was told that the result of my interview didn't prohibit me from applying to other positions. I wasn't sure how to read into that (and the recruiter was not helpful with that).
