Amazon Software Engineer interview questions

I only went through 2 of the 3 phone interviews. You really need to know your Big-O notation. Understand how a HashMap works. You'l have to write code down on paper and read it back to them over the phone. I had a few easy questions on threading, a question on how I would architect a web application for a car rental company (what would the app do? which objects would we have? I think he wanted to see if I knew what a DAO was, or maybe if I understood MVC).

Initially got contacted by an HR person. Setting up interviews was very fast and easy. After two successful phone interviews had an on-site interview. This interview consisted of about seven one-on-one sessions. the questions were from "Tell me about who you are and why are you applying to Amazon" to some technical algorithms and programming questions.
