Re tech bro: Personally, having worked for maybe half a dozen European-based tech companies, I've experienced two companies where I felt a bit out of the loop socially for not joining them when they played table football or went to the indoor climbing arena after work etc.

But they were always peer groups of people situated below decision-making level. So there was never anyone who could actually decide things that might be bad for my career, leaving me to wonder whether me not being a bro was what it was about.
