Honestly 95% of the time it was about technical stuff and I loved it. I've never worked at another company so active in shaping its own culture. Problems other companies had conditioned me to expect could never be fixed would often be gone in a few months because someone had made it their mission to fix.

That was part of something else I loved about their culture: there was room for anyone to move up if they could show they were creating value for the company. Other companies felt like everyone was competing for the same two promotions, but Facebook did not.

In retrospect though this also kind of looks like an unaccountability machine. If each employee must take independent action to justify their own paycheck in terms of their value to the company, most ethically questionable outcomes are the result of cumulative choices made by rank and file employees who know which side their bread is buttered on.
