Pros
Free coffee. Flexible start/stop times. Some opportunity to meet new colleagues that may be able to help you learn your job despite having no job description or training from your manager.
Cons
Poor management, lack of direction, laughable amount of training. Chauvinistic environment. You have to chase your managers for an annual review and in many cases people work there for years without one. No company credit cards and any travel you do that involves your job you have to pay up front and wait a few months to be reimbursed for. Expectation that you join in company meetings / team building exercises on your own time with no compensation or extra time off. They pressure you into doing volunteer work (on your own time) which causes a lot of resentment amongst colleagues. Overall, not a good place to work.
