Trustworthiness, more specifically having a clean record of integrity as opposed to just projecting a feeling of "you can trust me", is non-negotiable for me. If I don't think you're trustworthy, you're a risk to be managed and I can only really fit you into a Machiavellian mental model of "I can trust you only as much as our incentives align". I've had to work with people like that simply because it was out of my control, and it's tiring.

There are well-meaning jerks who are just rough around the edges but care a lot about doing the right thing. I might not like them very much, but I'll take a competent jerk over someone whose integrity I don't trust no matter how competent or polite they are.
