The process took 1 day. I interviewed at Amazon in Apr 2012
Interview
Just got a phone interview yesterday! It went great. My interviewer asked some resume questions, which were very easy going, and I was only given one problem to solve: one on object-oriented design (in Java). We worked on collabedit.com. The design was straightforward, although he was a bit picky about one of the methods I wrote and fed me hints for quite a while on how to perfect it. He sounded like he was in a bit of a rush as he told me he had a meeting to go to afterwards, and our conversation was wrapped up quickly. But I continued to work on the code afterwards and after he came back online and saw me, he very generously continued to guide me through it and after a while I got just about everything right. I just found out I made it through to another phone interview, so I'm guessing I did reasonably well or he was impressed by my persistence.
