I've personally interviewed a substantial number of candidates (phone screens and in-person interviews) for Amazon.

Amazon is very prompt about responding to candidates, but no decisions are ever made until the interviewers have a chance to sit down in a room together and discuss. So I don't know how the recruiter at the end of this account could have said half the things he is supposed to have said.

This account sounds like a specific recruiter made a series of huge errors and just kept on compounding those errors with bad decisions. That or there are some factual inaccuracies in the account.

In any case, my primary point is that I wouldn't write off an entire company due to what are likely the mistakes of a single individual, the recruiter who is supposed to be communicating with you.
