I submitted an application online and was contacted later that week about the position. I attended an information session that was very helpful in determining the responsibilities of the job and had an interview at the end of the week. The interview process was a three stages: a flow problem and two separate 45 minute interviews. The flow problem was not as difficult as I had feared going in as long as you don't over think it and I got 15 minutes to complete it. During this time I was in a room mixed with various Amazon employees and other candidates. The Amazon employees were really friendly and helped take the edge off and were dressed just as casually as we were told to come. After this we were called one at a time into either the math review/operations interview or the HR/personality interview. The operations section was focused on how I have improved processes in past experiences and things of that nature while the math review was simply them checking my work and changing a few variables to see if I could still do it. The HR/personality portion was pretty standard but many of the questions were geared towards Amazon's culture. Overall I found the process to be very well done from the amount of information provided to the friendliness and professionalism of the entire team.
