I had two one-hour phone screens followed by a full-day onsite interview loop. The questions were tough, but reasonable - relevant to the job and my past experiences and nothing ridiculous.
The interview loop was long and pretty intense. In true Amazonian fashion, expect plenty of probing follow-up questions. 'Soft' answers won't cut it - in the interview or while working at Amazon.
The company is data- and results-focused, crammed full of super smart people, and this is evident in the interview process.

Question 1
In my experience the questions were tough but fair, always challenging your analytic abilities and knowledge of the market & customer.
I applied online. The process took 4 weeks. I interviewed at Amazon (Seattle, WA) in Apr 2012
Interview
Had two phone interviews with Amazon for the Sr Marketing Manager position. They spent most of their time asking behavioral questions (such as, "tell me about a time when you had to ___") and presenting short cases. Case questions did not become very quantitative, but they just want to know how you would approach a problem.

Question 1
Suppose you were in charge of launching a new product. How would you approach it, and what is your go-to-market strategy?
I applied through a recruiter. The process took 3 weeks. I interviewed at Amazon (Seattle, WA) in Jun 2011
Interview
Very quick and efficient. I wish every company ran their recruiting like Amazon. They followed up exactly when they said they would, if not sooner. They were clear in the process, and very transparent when it came to presenting an offer and working with me to try to make some of the sticking points work out. I was so impressed by the lead recruiter - she was spectacular and should teach other recruiters how to do their jobs.
