Amazon Software Development Engineer interview questions

There were four back to back interviews from 8:30 to 12. There was either one or two interviewers at a time. All were technical. Topics ranged from algorithms/data structures, Java language details, object oriented paradigms, and program design.

Small detail, it was happening in hotel room, so was nervous as hell because of the atmosphere. However all interviewers were really nice to me except probably the last person which explicitly shown me that rumors about "working till death" in Amazon are not rumors at all. A lot of pressure in lat interview phase, but all other rounds were really pleasant. One more thing: interview was for 4 hours, without breaks. Be prepared mentally and physically.
