Amazon Manager of Operations interview questions

Got an email from the recruiter same day I applied. Set up a phone interview with a regional manager even though they were out of the country. The first phone interview with the manager was so horrible, we almost got into an argument. He kept interrupting me, and somehow wouldn't believe what I was saying. I was surprised i moved on to the next round. Had the math flow question, then three more interviews. Math flow individual, HR, Sr.Ops manager,and the site leader. I was offered an area manager position (which is one level below what i interviewed for). I declined.

There was 3 different interview panels covering the 13 principles they recruit off over a 2 hour Skype call. The format is STAR in which I was able to give an example to cover each point.
