I applied through an employee referral. The process took 1 day. I interviewed at Amazon (Orlando, FL) in Jul 2016
Interview
The interviewer is very nice. He would like to give you a hint if you ecountered some troubles. However, there are too many technical questions, which make the pace of interview too fast for me. The interviewer first asked some questions about me research, including some details and clarification some concepts. Then he asked several questions on basic statistics concepts. These concepts need to be interpretted to non statisticians. The questions gradually became complex.
I had a zoom call with the hiring manager. I was asked technical questions during the interview, such as "How do you compute the conditional median of a set of data points?"

Pretty fast and well-organized interview process. Scheduling was easy, communication of different interview expectations was clear, and feedback came quickly after each stage, which made the overall experience quite smooth.
