Pros
It's an entrepreneurial environment with no glass ceiling on your achievement, so there is no limit to what you can achieve. No guarantee you'll be compensated for it though. There are some exciting projects and trips available. Great place if you're a self-confessed workaholic.
Cons
It's a harsh environment, with long hours and lawful breaks are frowned upon. (Someone on trial lost their chance for taking an hour for lunch). Pressure to take work home with you, stay late, work while you fly - basically constantly. You're expected to bring in new business and the higher up you go, the more your job is at risk if you don't bring money in. The owner is a scary perfectionist, God help you if you can't read her mind and please her!!! Huge amount of cake, so don'y go there if you want to be healthy. I never had time to do anything after work and it's out in the sticks. Many employees got sick, including myself. So if you care about your life, health and happiness outside of work, then you're better off declining a job offer.
