Pros
Because you like being totally unsupported and on your own working for people who don't even acknowledge your birthday much less your hard work? If you like being in an abusive relationship though maybe this is a great place?
Cons
Total lack of support, total lack of any kind of actual management, like guerilla warfare we throw you into the fight and if you survive fine if you don't that's fine too. Oh and no matter what you do it's not good enough even if you're accomplishing something for them that they've never done themselves before. Also, there's no culture to this company. It has no values. They don't contribute to society in any way and don't support any charity or any cause other than making the 3 main owner/partners richer. Also, don't expect them to invest in you and help you grow your career at all. You'll never get any formal training or education and there's not career path here. Why would anyone want to work for these people?
