The process took 2 days. I interviewed at Amazon (Seattle, WA) in Nov 2009
Interview
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).
