Amazon Software Engineer interview questions

2 detailed phone screens (mostly data structures, access times, and language minutia of Java and C++), a flight/hotel in Seattle, 8 technical interviews mostly whiteboard coding/problem solving, a half hour lunch interview talking processes with the manager, and 1 hour HR interview. Interview questions ranged from permutation strings, to tree traversal, to block diagramming an elevator design problem. Concluded with a "we will call you", a cab that is.
