Amazon Senior Vendor Manager interview questions

Applied Online. 3 weeks later was contacted by Amazon H/R. After one 30 minute phone screen by H/R (successful) another 2 week delay ensued to set a 30 minute phone interview with the hiring manager. Hiring manager was first described as a 'he' but then the interviewer was actually a she. She called exactly at the bottom of the hour and there was ZERO introductory questions or personality questions. Nothing friendly. No opportunity whatsoever for personal banter. She launched into question 1, gave very little reaction then to Q2, Q3, Q4, Q5, Q6, Q7 most of which had nothing to do with my experience but had much to do with Amazon's existing processes. How you are supposed to know those as an outsider I have no idea. Anyways,she gave no verbal reaction as to the applicability of my answers, went deep dive on several of my answers into Amazon's apparently legendary data gathering and data parsing algorithms. She sounded more impressed with Amazon's processes than frankly I was. She left time for me to ask exactly 1 question of her (which I had prepared ahead of time) and she stopped the interview at precisely the top of the hour. Not a second over. Like a drill sergeant. Had no idea how I did and Amazon then played like a girlfriend that broke up with you and lost your number, email address etc. I have 20 years in tech. and they would not be mature enough to say - sorry you didn't advance to the next stage or we went with other candidates. Nothing. This was VERY discourteous and no the way to handle rejected candidates. Wastes the candidates time when you call/email back 3 or 4 times spaced 3 days apart. The process left a bad impression of me personally on Amazon. #notimpressed
