Amazon Risk-Manager interview questions

All questions were behavioural questions based on Amazon's leadership principles. All 5 interviewees were males during second round of interview which I would suggest that Amazon bring in a diverse panel during their hiring process. One of the interviewers asked 6 questions all at once during second round of interview which made me wonder if it was his deliberate attempt to fail me. When I asked back few simple questions at the end of the interview, he responded with some gibberish words beating about the bush that I really could not comprehend. Made me wonder if Amazon really lives up to its leadership principle of "Hire the Best!" If Amazon wants to hire the best, start with better and diverse panel of interviewers.
