Original comment started by stating your many years of experience and noting that interviewer was much younger. Then complains about being asked to do coding. And then, based on just those two, saying that you know you'd be unhappy working with people like him.

Amazon isn't great environment in most of the pockets of the company (haven't worked there, but worked with a lot of people who came from there), so it's quite possible that you "dodged the bullet".

But only when pressed, you start to complain how interviewer is immature, arrogant, rigid. That's not what you originally stated - you had issues with an interviewer age and being asked to do coding. I'm not trying to defend the interviewer - it's very possible that they were bad interviewers - big tech companies push people early to start interviewing. But things that you complained about initially make it sound like you maybe also not a very pleasant candidate to work with, that comes into the interview with a lot of bias.
