Pros
Compass was, overall, an enjoyable place to work. I really liked my team - the crowd skews young, but they are smart, hardworking, and collaborative. I'm not sure about others, but I personally felt that my compensation was "at the high end of fair" - not quite "generous," but aligned with the market. Medical benefits are included unless you elect a Cadillac plan, and the free ones are pretty good - not HDHPs. The office has catered lunches every day, and if you're petty enough to complain about the quality of the free daily catering, then please tell your personal chef I say hello. Office is dog friendly. There are events, etc., if that's what you're into.
Cons
Extreme lack of transparency from leadership. All-hands meetings are frankly a joke: they put the CEO or another C-Suite leader on stage and deliver a motivational speech, when the reality is extremely different and many are worried about job security (even pre-COVID.) Performance review processes are extremely convoluted and can run for months beyond their allotted time. This wouldn't be a major issue if performance reviews weren't also directly tied to raises. They are rigidly structured and managed extremely poorly - I would not count on getting a raise or receiving a bonus, even if the bonus is built into your comp structure, even slightly. Treat getting your bonus like winning the lottery. It's that hard - not because performance standards are so high, but because the system itself is like a Rube Goldberg machine.
