Amazon Operations/Area Manager interview questions

There was a phone interview, followed by 4 separate in-person interviews back to back. Each one had a different role in the company including Operations, HR, Customer Service, etc. I also had to complete a math flow question and wright a few short case study question responses, which were reviewed with me during one of the interviews.

online application. online tests the a phone interview (HR) then face to face with 3 different persons (1 HR + 2 Ops) at the same location; it took whole morning.. Interviewers attitude were very rude and unprofessional; phone interviewer was 2 hours late (I had to call !) and face 2 face interviews started 2 hours late. They didn't even bothered to say "sorry for the delay". We were able to see them having pizza in another room. During interview two of them were yawning, and the other one was more interested on what was going on on the street. Not impressed AT ALL!!!
