Applied online through a referral in October. I heard back a few days later and set up a phone interview with the recruiter. Next, I had a phone interview with the supervisor about two weeks later. About a month later I had an in person interview in the office. The in person interview lasted from 9 am to 11:30 am, and I met with four different people back to back. The interviews are challenging, so I recommend researching the Amazon leadership principles and thinking about how they relate to your own experience. Think of an example for each leadership principle.
