I applied through a recruiter. The process took 2 weeks. I interviewed at Amazon (North Reading, MA) in Oct 2015
Interview
Amazon Robotics uses situational behavioral interviewing. Each interviewer is assigned a topic area and asks questions from your past experience on how to you accomplished or handled that area. How you answer and what they hear is how they predict how you will work in that environment. Each interviewer enters their opinions in Amazon's ((in)famous review system then they get together with the hiring manager.
The highlight of the interview going into a test area and see their robots in action. The robots are used in amazon's fulfillment centers to bring bins over to a picker to grab an item for a customer's order. Very cool.
