Pros
They send many job opportunities depending on whether or not you are willing to drive out to that area. They always seem to have positions for tutors.
Cons
The worst part of landing the position is that they don't let you know that this doesn't mean you'll get a job. After months of not landing a gig, I had to quit. I didn't even quit, I stopped replying to their emails. They made me go through this long interview process to not even consider me for a job, that really says something about the company. Don't even bother applying, not worth your troubles.
