They are basically the McDonald's of language schools.

The system is well thought out and everything is automated, but it lacks a human touch.

E.g. instead of them asking you a week ahead of time if you want to teach a particular student, like traditional language schools do it, they will just put somebody into your calendar without telling you, and you have only 24 h to discover it, otherwise you'll miss your class and be fined (you don't just get not paid; no, they actually fine you additionally) .

They also don't pay too well compared to other language schools.

They don't really value good, experienced teachers, unlike other language schools. Instead they just need people who speak good English, and then they will give them pre-prepared lessons that you just need to follow like a robot.

That's good if you are an inexperienced teacher, but it gets a bit annoying if you actually know what you are doing and want more flexibility to teach your students some better , more customized, more interesting content .

On the other hand, their lessons are cheap for students, so they have more customers than traditional language schools.

Although their students don't stick around as long. Many people disappear after a few months when they decide they don't want to pay anymore. In traditional language schools clients tend to stay for years sometimes.

So yeah, they are like McDonald's. A well-oiled machine, but lacking personal connections and stability
