Pros

There are some really top people there. It's always good to work on open source. The pay and benefits are good, and regular bonuses.

Cons

I expected a relaxed and friendly startup kind of place. Alas, it was by far the most "corporate" and yet least efficient environment I've ever worked in. As one example, it took IT months to get me a work computer. They're now spending $100m/yr on developers. It's very hard to see what that's achieving. Seems as if top talent is wasting its time there compared to what's being achieved at Google, Apple and others. One reason is massive technical debt and an insane codebase.

Pros

Great health insurance benefits. Literally you pay nothing per pay check. Also parental leave is 6 months which is rare in the US. Wellness days were nice too.

Cons

Lack of black people in and promoted to senior / management positions even though there are many qualified people to be there. Also management cannot make decisions. They are leaps and bounds behind the competition and many lack competence.
