Pros
Your co-workers will be cool. You'll get along with them. If for no other reason, than because you can complain about how much you hate the place. They have free candy, which is nice.
Cons
Above all else, the stress that will be unwillingly placed upon you. There is a reason the turnover is so high. Every week, at least 5-10 people quit/get fired. In an office of less than 200, that's insanely high. The job of HR, almost exclusively, is to find new hires, weekly. No one stays longer than 2 years. And if they do, it's only because they either kiss someone's "bum" or care only about money (not their free-time, family nor health). Trust me; I know things might be tough for you, and you may need a job/money, but this place really isn't worth it. It doesn't deserve you. You are better than this place. Keep looking.
