Disclaimer: I am women, but never stepped the foot in CA. Geography matters. I see ping pong tables and free beer as a red flag of sorts and seek workplace that is more formal. The idea is that the less it attempts to be personal/cool/cultural the less personal things (e.g. gender or peoples attitudes/biases or who-likes-who) matters and the more actual work matters.

I've been reading more about this lately. One story that struck me was about a journalist whose newspaper was purchased by a tech company, and the culture changed. She went from having a private office to working in a huge, open office environment. I'm putting this together from memory, but I remember her talking about how strange it felt to have so many people able to see her screen, not knowing where to put her bag if she wasn't at her desk watching it, and having to take it with her to the bathroom (feeling somewhat self conscious about how her more frequent trips appeared to her younger, generally male coworkers).
I'm starting to think that there's something more insidious going on with an almost aggressively enforced "open office" culture in high tech. I also think tech is starting - but just barely - to wake up to the the value of the formality that we discarded and disdained.
I'm really mainly interested in hearing more from you on this, if you're interested in writing more about it.
