I've worked for real jerks before. I don't think the economics of it work out. This being said, you learn a certain stoicism in the face of it. If you catch a real rant, a stone cold "You finished?" at the end might be in order.

Don't get me wrong, I've raised my voice at people but only after they've persisted in a particular error for months, after receiving many many external reference to why it's an error.

I've no interest in working for a Bezos-type because I see that as a "cult of personality". It's something people have to work around.

If people are risk averse to sharing ideas, then you'll get fewer of them. Perhaps that's a good thing. But it costs very little to learn to provide feedback in a non-confrontational manner.
