They pay a lot of money to build that persona. Unreadable this, unbeatable that, sailboats, fighter jets, etc. I was in a meeting when some SVP dude called on us. His big story was how when they bought Sun they hit their target for shutting down EMEA Sun operations, but in doing so fucked their customers and they couldn't ship product for 3-4 months. It was pitched as a "good" story.
I have no idea what the culture is like inside. I'm exclusively commenting on how they portray themselves to people sending them bags of money.
