I had two phone interviews, first with the recruiter and next with an Operations Manager. At the conclusion of the second phone interview a date was set for me to have an on-site interview at one of the fulfillment centers. All travel was arranged and paid for by Amazon. On the day of the interview candidates arrived at 8am and started off by taking a math flow test. The test given was exactly the same as previous posts. The first interview was with 2 people and I first had to draw on a white board and explain the math problem. After they were satisfied with the explanation, they threw some curve balls to show I could think on my feet. I was then asked to go into more detail on scenario based questions I was required to answer and send in prior to the interview. That lasted about 45 minutes before the next interview which was one on one and was primarily about leadership and also lasted 45 minutes. The third interview was two interviewers and was a slew of questions about real examples of the relevant skills and "why Amazon" type questions. The overall process was pretty mentally exhausting but they were fair and very honest about the pluses and minuses of working there.
