Amazon Manager Operations interview questions

Was recommended by a friend. Soon after the recommendation, I received an email asking when would be convenient for a phone interview. A few days later, the phone interview occurred and I was asked standard STAR based questions. About a month later I was invited for an in person interview. It takes place at a fulfillment center. It's a 5hr process. 1hr to tour the facilities and then 4 1hr interviews. The environment is very relaxed. Everyone in polos and jeans. If you wear a suit to this interview, you will be extremely overdressed. One of those interviews is based on a math flow question. Pretty straight forward but I can see how people can make mistakes on this one. Check online before you go to get a feel for what the question could look like. Also before you arrive, they send you two questions. You have to answer one of them and send in to the recruiter before your interview date. Make sure you think of an answer for the other one and be prepared to talk about it during the interview. Also read over Amazon's leadership principles and be prepared to talk about which ones you align with the most and why. After all the interviews, they instructed all of us that we would hear back by the next week.

I applied the position through university recruiting process. There were two rounds of interviews. Two 30 minutes interviews in each round. Because it was on-campus interview, it was really efficient. First round on Monday, second round on Tuesday, and got the offer on Wednesday.
