Pros
I really like the pace that we're working at -- there's so much going on, and there's a lot of inherent trust in people to run with what they're doing. Policies and red tape in previous companies sometimes left me feeling a bit stifled about what I was able to work on & share, but there really is a sense of openness at Facebook, not only in communication, but in the ability to jump into projects that call out to you as well. And beyond that, the people really are incredible: smart, fun, unique, and passionate about what they're doing. It's hard not to get excited by the people alone!
Cons
The pace *can* be a little crazy -- one of our values is moving fast, and we definitely do that -- and generally that's a huge pro to working here, but at times, it can be a little much. There are definitely good policies around PTO, and the environment *is* understanding about balancing work & personal life, but that's ultimately up to the individual to carry out, which can be difficult to do in practice.
