Take a look for yourselves, Teachers-Teachers.com
A few things stand out for me, which I intend to bring up in the interview.
First, I'm impressed that their recruitment methods work on the same tools that their schools use- the automated pre-interview, thing, etc. It shows confidence in the system. Then, reading through their testimonials and partnerships; it looks like they do good work.
But then, looking through their method of billing schools. Schools pay an annual flat fee, based on the number of divisions, or the number of schools in the district, etc. One school? $950 a year. Hire as much as you want, post as many jobs as you want.
This company- it's good stuff. I'd be happy to work for them. Even without this desirable a job, I'd work for them.
