I interviewed at Amazon Fulfillment a year ago. I got the opportunity through a friend who works at Amazon. The overall experience was positive. I had 3 phone interviews if I am not mistaken. One of them was HR related, nothing complicated. Answered some basic questions. And the rest were with the Managers in my future position, to be exact he was my boss-to-be. Well, it was very hard for me. Even though I prepared I got so excited since it was a phone interview and apparently it is not my cup of tea. They are however very straightforward in their questions, no hidden agendas. I wish I was able to get to the face to face part, where I am sure I would have gotten an offer.
