The process took 2 weeks. I interviewed at Amazon (Seattle, WA) in Aug 2011
Interview
The first interview was a written interview where the recruiter asked basic questions. The second interview was with HR as a screening interview to get to know my background. The third interview was technical and harder than I expected. He first asked me some basic object oriented coding questions, then asked me how I would solve a problem and finally asked me to write the code on paper and read it back to him line by line.
The interviewer was looking for a very specific method, not just the right code that meets the requirements.
