I applied through a recruiter. The process took 1 day. I interviewed at Amazon in Dec 2012
Interview
I went to Amazon for a on-site interview. It is a group interview. Three people are assigned into a group and assigned a programming question. The question is separated into three parts. Each individual can choose one of the parts and use any language you want. It gives almost four hours to finish the task and during this process, you will be interviewed by an employee about thirty mins.
