I applied online. The process took 1 day. I interviewed at Amazon in Dec 2009
Interview
Did not prepare - went in cold - was in fora surprise. They are not like your typical SE interviews - post-interview, read more about google interviews and how they are interested in CS topics - trees, data structures, algorithms, etc. I do have a personal interest in such topics though wasn't prepared for the interview. Did ok, but not good enough. The interview took an hour and I had to send a code-sample within an hour post interview.
