Pros
Company is very financially stable, the office environment is good, they truly have some great people who work there, extra little perks here and there are nice. They have established a very clear "why," and honestly, their product is fantastic and their customer base is enthusiastic and excited about the product. This company WILL continue to be successful, no question. They're a leader in their market and thought leaders in the space. If you mostly care about working for a "winner" and a successful company, this is the place.
Cons
Culture is not what it seems, it's very limiting. You can't work too much (over 40 hours), but you'd better be there 8-5. In some roles, you can’t even come close to getting what you need done and are punished for working more to try to make people happy. You are not trusted to be a professional adult and get your work done unless you’re there at prescribed times. Be prepared to walk on eggshells. Fall in line, or else. Some of their best employees are let go with no announcement or warning, just for seemingly disagreeing or trying to make things better. This is not only recent, but as a pattern of behavior. Honestly, it’s better for those employees, as they always seem to come out better on the other side. They don't reward type-A go-getters who see problems and solve problems, they reward sheep who stay with the flock and don't ask questions. Very difficult to get things done. The founder has to approve every last penny spent. For departments that have to spend money to function, e.g. marketing, it’s excruciatingly painful. Way too conservative and tight. It's turned highly political. Compensation is low market and forget advancement opportunities, they just lean on their “great places to work” awards to get people in the door. They "don't believe in titles," and keep the organization as flat as possible. When you do get advancement, you "lead from where you are" instead of getting an actual promotion and pay increase. Your reward is just more responsibility. In their defense, they're getting slightly better in this area (because they have to play the game to get and keep talent), but it's still not real-world. They lean on hiring young people, mostly out of college, who don't know much better.
