Which is what I did.
This is also not one persons perspective, but a common perspective in Seattle, so common that I knew about it in 1996, repeatedly heard horror sorries for the next 10 years ,and still went to work there after hearing horror stories from other ex-employees. Yeah, they caught me at point where I was a bit desperate.
In seattle, the horribleness of working there is pretty widely known.
Not sure why its so shocking and unbelievable here on Hacker News.
Even if we were talking about 100,000 engineers, though, I think it's fair to make a generalization about the culture. Companies have a lot of autonomy in deciding the nature of interactions between the employees as a group, and especially between employees and their superiors.
Also, people make similar generalizations all the time around small towns and neighborhoods (with often dubious accuracy, sure), but the only difference is one's structure develops bottom-up, and the other top-down.
