Until a few years ago most projects at Netflix were done with a handful of engineers ( <= 6 ). A dozen people working on something would have been considered very large. Four dozen would have been considered a company wide effort.
Netflix was famous for that, too -- no RSUs, just straight cash, and we'll fire you if we think you can't deliver.
100s of devs would essentially be their entire, company-wide, operating budget; it's gotta be like 10-15 people tops on these things.
The culture was and still is as you have described, with massively high pressure, "radical candor" taken to arguably very unhealthy levels, and with no hesitation in firing you. This is a major reason why, despite the fact that I am a video engineer with a film background who lives walking distance to 2 of their campuses and has a great amount of respect for their technical achievements, I never apply there.
