Amazon Developer interview questions

5 1 hr phonecalls ( with as far as I remember about 7-8 people) After last phone interview, which I felt I failed miserably, I told the agency that there was no way they'd hire me as I was awful for that call, they offered me the position. I think they were basically trying to find out what I didn't know rather than what I knew at that stage.

Started with a phone interview, asked simple questions about background, coding experience, etc. Second phone interview logged onto a website to do some programming with them. Questions usually about data structures, they asked me to find the two largest non-equivalent but structurally equal subtrees in a binary tree. Interviews in Washington were of the same sort, very similar to interviewing with Google.
