I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (London, England) in Nov 2012
Interview
They contacted me on LinkedIn and we planned a first phone screen where the interviewer asked me about my past experiences.
After that, I had a technical interview where he asked me to solve problems over the phone and think aloud so that he can understand the way I think.
