Pros
Great place if you're on your first editing job. You learn a lot of useful techniques and the training will polish up your grammar.
Cons
If you're an experienced editor, there are better much places out there. They treat editors like school kids or worse, like vermin. The salaries are abysmally low. You're cooped up in a tiny bay and are expected to finish a lot of work in ridiculously little time. It's ALWAYS the editor's fault and never people who assign you work. The manager has a penchant for yelling at people. They are always UNDERSTAFFED because of the editors who leave or who are let go. Because of this, you never get any leaves. God save you if you do take an unplanned leave (You will be yelled at). They'd rather OVERWORK an editor than hire another hand. You WILL work for 12 hours a day. Again. great exposure if you're starting your career off. Side note: Everyone gets really sloshed at company outings. It's the only way to let off steam. Oh, and every editor is supposed to sign a year-long contract. Places that are a joy to work at won't need a contract to keep their employees on board.
