Amazon Practice Manager AWS interview questions

Highly disorganized group of people! My resume was submitted for the Practice Manager role. The first phone interview was scheduled with person X, but when I joined there was person Y on the call. Was told person X couldn't make it, well that's fine! The interviewer dove right into asking questions. 1) Tell me which service in AWS you will use for moving schema? 2) Tell me about MTTR? Me: Hold on I applied for Practice Manager, this seems like an Architect interview. Interviewer: Ahhhh there seems to be some mistake, guess we'll have to reschedule. Failure point 1: Replace interviewers so random that they have no clue on who or what role they are interviewing for. Phone screen 2: Goes well tested on Principles and some business acumen questions. In-Person Interview: Met with 5 different interviewers. However, there was one peculiar character who wasn't fit to be an interviewer. He: Tell me about 2 things that you use to convince customers on cloud adoption. Me: Cost benefits and Business Agility. He: Goes on and on and on stating that Cost Benefit isn't a good pitch. Me: I hold my fort and explain for 20 mins on scenarios where the cost comes in play. He: Well i disagree on Cost being a good factor Me: Im firm on my choice and stand by it. Where Amazon Principles Fail in testing a candidate!!!!!!!! Principle A says: Leaders don't commit to something because they are being pressured or influenced by leads/team. Principle B says: Disagree and Commit. Agony: Which principle did this interviewer want to test? Advice to Amazon: Don't hang on to principles that are broken or conflict the existence, what you'll end up getting is a bunch of rude characters who will hire like-minded team and wreck the company. Got the offer, but SORRY im not going to work in a broken environment. It was nice chatting with some great people though!
