I applied through a recruiter. The process took 3 weeks. I interviewed at Amazon (Palo Alto, CA) in Jan 2015
Interview
Two phone screens, onsite "loop" with four team members and one "bar raiser." Each interviewer will focus on at least one of the amazon leadership principles. Questions about amazon itself, the customer, etc. Process very smooth from phone screen to onboarding. It's VERY VERY VERY common for a first interview on the phone to not result in a good fit, but if the screener likes you they will definitely pass you to another group.
Interview questions [1]
Question 1
Standard product management questions but with a cloud focus. How do you work with engineering, etc. How would you price a service in a new region, etc. Then a semi-technical interview with a bar raiser. Let's build X service in the cloud... Lots of focus on the Amazon leadership principles, which IMO are a great set of principles to have an example of in any interview. There's a reason every single customer loves amazon.
I applied through other source. The process took 6 weeks. I interviewed at Amazon (Berlijn) in Feb 2014
Interview
We were sitting in a large room with a lot of people. The start was a bit rough but got more easy later on. They actually invivted me for dinner which was really nice and I enjoyed that.
I applied online. The process took 4 weeks. I interviewed at Amazon (Irvine, CA) in Aug 2015
Interview
I was contacted by a recruiter, passed a phone interview and was asked to submit a writing sample and to interview live. The live interview was very lengthy (more than half a work day) with multiple team members and included a lunch with a buddy from Amazon.
Despite the effort I went through, the Amazon recruiter did not call me back as scheduled and send an email rather than calling saying there was "trouble" with their line.
