> I would laugh, but I've seen this up close and personal and people like this are more dangerous than they might look.
A way in which those people are extremely dangerous if the organization allows them to thrive with such a behavior is that smart, productive employees will realize early on what's happening, and will follow suit in order to not fall behind. Entire teams can get poisoned in 6-12 months just like that.
I'd like to contrast that with current HR practices. Why is it that HR departments (as far as I can tell) focus on hiring "the best" or "the best available", while it would be more important, easier and cheaper to simply avoid "the worst" (aka this guy).
