Pros
There are some really great, talented people at Unity who you get to work with on a day to day. The product has a lot of upside although sometimes it feels like the pieces will never quite fit together properly -- like the promised land is visible doomed to be unreachable. Benefits are solid.
Cons
Big disconnect with uppermost leadership. Sometimes you wonder how people land in these jobs. The toughest part is that in terms of comp (especially equity) the top most make away like bandits while several layers below get peanuts in comparison despite being the foundation of the value. There seem to be a lot of people director through VP where it's unclear what exactly they do and what value they add. It's frustrating again because there is a lot of talent and a great product, but key players seem to be letting the broader company down.
