That looks like a meerkat? XD

entitled, self-absorbed, rude, needlessly aggressive, intolerant and generally fucked

I think most of them most of the time think they're being assertive and setting boundaries.

And if the colleagues genuinely felt that way in the interactions it's entirely possible he won't be in that job for too much longer even if he is absolute childhood besties with the ceo of that company (if not outright fired they'd move him somewhere else).

Have dealt with a client like that before, he was actually more horrible to sibling dearest than he was to me (probably because I kept stonewalling him hard, sometimes just because my brain would glitch out in the moment and I would either not notice til a few seconds later and only from sibling dearest's expression, or not at all til we talked about it later, sometimes intentionally). And the above was pretty much what happened.
