Amazon Software Development Engineer interview questions

Communication and planning was smooth, and I was scheduled for four one-hour interviews. Each inwerview was a one-on-one with a software developer. There were a few personal questions, then technical questions on different topics (algorithms, OO design, testing). At the end of each interveiw there was a chance to ask them questions about working at Amazon. The whole process was very informal and pleasant. After the inwerviews i quickly received an answer, but after that the process was somewhat slow.
