This shows to me that you have a lot of faith in these companies that I can't share based on my own experiences.

My experience is more like: the defining characteristics of what gets you more opportunities is personal attachment to the boss. They like you? You get more. The whole performance review culture, as an example, is based around phony justifications around this. They get to re-define what "getting results" means to favor buddies. This is the only determining factor, period, and people come across to me as absurdly foolish when they believe something else.
