Amazon Sr Project Manager interview questions

I was contacted to do two 45 minute back to back interviews. Almost 10% of my school's MBA class was contacted and did the interviews. I was invited for on-site interviews. It was 4 interviews of 45 minutes each. The 3 consisted of situation questions. "If you were the manager of this product what would you do if this happened?" Only 1 of the interviews was conducted by a senior person in the company and had questions such: -> Tell me which is an ideal culture for you? -> What do you wanna do now? -> What is the most important accomplishment?
