Amazon Software Development Engineer, interview questions

2 Telephonic interviews and 3 Face to face interviews. Mostly focused on data structures and algorithms. Very particular about complexity of programs.

It was a recruitment day. There were 4 1:1 technical interviews. Basic algorithm questions - circular linked list, anagrams, evaluating arithmetic expression and flattening a tree and writing to a file. They were pretty simple and straight forward. The interviewers try to help you out with the answers. Did a couple of rounds very well, and a couple went ok, which I guess is the reason for rejection.
