The culture slides on Netflix's job site do make it seem like a scary place to work but at least they are transparent about what it's like to be employed there..
Personally I wouldn't expect "a culture of fear" going in but I'd at least have a pretty good idea that I need to perform, and produce high quality stuff, to survive there.
I mean, company culture is never really the problem for jobs I've signed up for as long as the company is honest about the situation. If I'm told it's a 9-5 and I find myself pulling 60-70 hour weeks (or the reverse scenario where I'm it's inferred that my Type A personality is going to fit in and I can make a big impact and it turns out to be a boring 9-5) that's when I get upset and start looking for new opportunities.
