I initially applied online and received a call from a recruiter approximately 3 weeks later. He asked a few basic questions and offered to set a date and time for a full phone interview. The phone interview consisted of a math question which was sent in advance via email - no problems here. The phone interview lasted approximately 30 minutes and I received an offer to interview in person. The onsite interview was scheduled at one of Amazon's fulfillment centers in a different state from where I lived at the time. Amazon paid for my airfare, hotel, transportation, meals, etc. As other reviewers have mentioned, it is worth going to the interview just to see the operation. Amazon interviews potential managers in groups and there were 8 people in my group. We were escorted into a conference room with our recruiter who gave us a new math problem - again, no worries if you know basic algebra. We were each given a tour and two 1:1 interviews but others have had different experiences - YMMV. The building where I interviewed was recently opened so the tour was incomplete but I was given a good idea about the work environment. Amazon likes to show off their best buildings during the interview process so keep this in mind if you interview at a new building and decide to work in an older building. The first interview was with an Area Manager who had been with the company for less than a year. She was very friendly and asked questions in the STAR format. I felt at ease and she didn't try to pose any difficult or tricky questions. I was able to read her expressions easily and knew the interview went well. The second interview was with an Ops Manager who happened to be a former Marine. He kept a poker face and we discussed the math problem. At some point your interviewer will change a component of the question and ask you to recalculate. Just stay calm and explain your thought process - there are no tricks. He also asked me a few questions about my education and offered to answer any other questions I might have. Overall I don't have a single negative thing to say about the interview process. Everyone was extremely friendly and seemed to be genuinely interested in the hiring process. I should point out that your interviewer can be anyone who has completed Amazon's 4-5 hour hiring course. This does not make them a seasoned/skilled interviewer and a few of my colleagues have had some interesting experiences.
