Amazon Manager - Operations interview questions

The Recruitment HR were responsive and were professional however the person who interviewed from Operations team was very unprofessional and rude. The interviewer even before it all started said 'this isn't the only thing he does and he is a very busy person and will have to answer with in a his time line', I do understand the time line however the initial part was really weird. Why schedule an interview when they didn't have time in hand. Then on it was more of open ended questions and the interviewer wanted a closed ended answers. I did send in a feedback as well stating the experience to Amazon however i didn't get any response on the same.

Hiring process was stringent and had multiple rounds of discussion with detailing and drilling deeper on experience on people management and testing. I had 5 rounds of interview includes technical and non tech. Mostly on scenario based questions
