I had 2 phone interviews with Amazon. I was invited to in-person interview after the first one that lasted about 2 hours. Couldn't go to Seattle at that time, so I declined. Recently, I had interviewed over the phone/online coding again. Haven't heard back yet, perhaps it's not been long enough. I feel their phone and online interview is a fair game for entry level position, consisting mostly of testing of general knowledge of data structures and algorithms. Trees, hash tables, list, algorithms used on them. I felt the interviews were testing knowledge of this subject matter mostly and questions were how to optimize/improve the algorithm also. Nothing too tricky or unusual. They didn't care which language one would use either.

The interview process consisted of an online assessment followed by two technical interview rounds and one behavioral round. The technical rounds focused on Data Structures, Algorithms, Java, and problem-solving skills. The behavioral round covered Amazon Leadership Principles and past project experiences. The interviewers were professional and the process was well structured.
