I worked only in one big tech company, but my impression is that they try very hard to have a consistent work culture across the company. Everything was super standardized and controlled. There's also a high turnover so even if there's a bunch of senior people that maintain a sane culture, they'll leave eventually.

As for director/vp, I barely know mine. I think this guy just wants to keep his cushion job and deliver whatever BS his managers ask him. Just like the rest of us really...
