Pros
You can get some professional editing and writing experience. Some of your coworkers are nerdy like you, and that can be really fun.
Cons
You work for a company that is always trying to find ways to pay you less. They care about quantity more than quality, and they aren't afraid to make you work overtime without compensation (there's a reason they pay salary instead of hourly). If you absolutely need some experience so you can move on to a good career in writing or editing, it can serve as a small stepping stone. But don't let yourself expect anything grand or long-term here, as they have a tendency to throw out even their most loyal employees like trash.
