A friend and ex-colleague of mine joined Facebook recently - I visited him after ~2 months and he really loves working there. His words: the culture is great, most of the "mundane" problems are already solved (communication, monitoring/alerting, tooling, etc.) so they can focus on real problems and the company is very strongly technology-led. We were working together in a mid-sized startup before with also amazing culture and cool guys around. Now, your questions (I'll answer what I can): 1. open, transparent, very technologically led 3. he feels the opposite 4. yes, definitely, the way the company works enables this (teams come up with their own projects, agenda) 6. it definitely feels like a huge company but it's not bloated. Bottom line: if you're thinking about joining, I'd recommend doing so, even if you won't want to stay there for many years it's going to be an awesome experience and learning plus you get to see from the inside how a huge but still engineering-driven company works.
