I've had similar experiences. I interviewed for three different roles and backed out of all of them. The hiring managers ranged from OK to egotistical, so it's ironic that one of the new principal is "lead with empathy". What was interesting during my process was that, by the second time, I started to call out Amazon employees for not abiding by the principals they asked me to understand prior to interviewing. Not only did they not "earn my trust" during the process by not following through on expectations they set for timelines in every instance, but when I brought this up ("have a backbone") the employees seemed to take offense that I'd have the nerve.
At this point I have no intention to apply or reply to any recruiter looking for Amazon candidates. It seems as though the majority of their principals are lip service, or I've been unlucky enough to find areas of AWS that I would clearly not want to work in anyway.
