Pros
The executives don't just say things to look good, you can tell they genuinely believe in their efforts, and hoping to transform an industry. They care. I can say that from the top to the bottom of employees, this company has a culture of caring. If you like to work, and find enjoyment in being more than just a cog in a machine, Compass would fit you. You definitely have to strive for excellence, because they don't accept anything less. When this company sees a flaw in how they're doing things, they laser focus their efforts to fix it. Compass is extremely nimble, and always craving feedback to improve itself. The company's values are the values that every person should strive to achieve, in all aspects of life.
Cons
There can be a few egos. But maybe that's what you get when you only hire excellence. Also, as everyone else has said, be prepared to move fast and work hard.
