Not like I know a ton of Amazonian white collars, but it still seems like a worse place than average. My wife's team had a guy leave a few years ago and almost immediately come back because it wasn't worth it. They seem to have a hiring problem that probably leads to all the stack ranking and mandatory attrition because they can't assure the people they hire are qualified. I interviewed with AWS once, but didn't accept, and the experience was frankly just bizarre. I was thrown back and forth between people with roles in all manner of completely unrelated disciplines. One woman accidentally hot mic'd herself when she didn't realize I hadn't signed off yet and complained that she had no idea what I was talking about because she hadn't had a technical role in 20 years. They gave me the option to talk one on one with a developer who would have no input into hiring and she told me, as the chosen spokesperson for AWS, that she didn't like working there and probably wasn't going to stick around, but it was her first real job after college so there she was.
Ironically, on the other hand, when I was first leaving the Army 15 years ago, the enlisted guys leaving at the same time were overwhelmingly all looking to work either as roughnecks or in Amazon distribution centers because they paid so much better than anything else you could expect to get hired for with no qualifications other than willingness to get beat up and tired.
