Amazon Software Development Engineer interview questions

I was selected to bypass a phone screening and attend an on-site interview with a large group of other interviewees (though the interviews itself were on an individual basis). The interview day consisted of 4, 45 minute technical interviews each conducted by a different interviewer. Coding on the whiteboard is required (or sometimes on paper), and each of the interviews you are given a complex coding question that you must solve in front of them. These questions may be relatively simple if you remember all of your algorithm knowledge from college very well, otherwise you must go in with a significant knowledge of trees (binary and binary search, etc), data structures in general, searching and sorting algorithms, object oriented programming, just to name a few.

Called at the exact minute and immediately started technical questions. Interviewer was asking for the basic layout plan of the program. I didn't have to read any specific lines of code. You can ask questions at the end. Articulating your thoughts are most important here. You can have a few minutes to think about the layout. So I would recommend having a sheet of paper in front of you, draw out what you need and spend the rest of your time thinking about how to translate that picture through the phone. (I did not articulate well, so I had to go over what I said a lot)
