I'll be downvoted to hell for this. I'm from Europe, I've worked for several SF based companies (some hired, some through acquisitions) and can confirm that , despite there are some really, really smart people there are also a lot of people that have no clue what they're talking about, as in most places you have a mix of it. But almost all of them are incredibly arrogant and most have an incredible tendency to take decisions based on what's important for their CV and there career and their podcast and their YouTube channel than for what the company or the problem at hands needs. I'm not sure I'm taking again a job for a west coast based company.
