Ask HN: What is it like working at Netflix?

I'm considering accepting an opportunity at Netflix, but I'm not sure what the environment is like. Can someone at Netflix or who has worked at Netflix give an objective description as to what it's like there? I've read that everyone there is very smart, and the bar is set extremely high. I am very good (amongst the top people in every group I've worked at), but I'm not a god so I'm worried that I'm not good enough and that I will be let go within a month. Are things really that competitive and cutthroat as I've heard, given what I heard was a 10%/quarter turnover rate?
