Pros
For quick money, not ever a career. If you were brand new out of college, needed a job, sure, go ahead and get some experience. But don't stay there long, as they will use and abuse you. Nothing is good about the place, other than they always have money, that unsuspecting people donate to them. They don't use the money for it's intended purpose, nor do they feel any remorse for using it for their houses, their cars, their laptops, their cell phones, their utilities, their food, their kids' needs, their complete costs- and you thought they were just "poor" ministers?
Cons
Incompetent ministers put in charge, switched every few years, church people given preferences over other more competent persons. Poor pay, no recognition of talent or any advancement. Poor moral there. They take really ignorant people that are generally failures in real life, give them a quick education and call them ministers, ready to change the world. They are then thrust into management positions, where they supervise large budgets of cash donations, and numerous employees. They are not qualified to do either. Worse, no one supervises the management, so they can run wild and destroy everything that's done, or worse yet, do nothing, which most are really good at.
