This was my experience of Ballmer-era Microsoft management hires at my previous company. They were the perfect combination of narcissism, manipulativeness, toxicity, and above all else, idiocy. They did a lot of damage, probably irrevocably. They were know-nothing bullies who liked to yell if you ever questioned them, completely convinced of their own superiority. I've heard a lot of similar stories about these people at other companies. It's a shame what people like this get away with.
