Pros
I've been teaching online for quite a long time, it's my full-time job and I've changed so many companies, wanted to try different things. Only at ME supervisors know who you are, know your face, don't address to you only as "teacher" and that's hard to find. Try sending a message to some of the other companies that something should change, let's see if they'll answer!
Besides being a teacher, I am also an interviewer at Magic Ears and I know the process, that's why I can say-if someone tells you they've been treated badly during the interview, that's quite a lie. The company has requirements like every other company, that energy part-for some not too big of a deal, for others it's too much, it all depends on you and your ability to adjust. But, they give you EVERYTHING you need to prepare, they tell you what to expect and exactly what they want, so many videos, a Facebook group to answer Qs.. literally everything. You'll know exactly what you need to do, it all comes down to whether you can. I see bad reviews from people who simply couldn't do it, not cause they are bad teachers, but just cause the way we work is not for them, we can't all be the same and able to do the same and that's absolutely okay! That's what people should realize. Bad reviews travel much faster and are much louder, unfortunately, even when there are more positive ones. My advice is-apply and see for yourself, the only way you'll know for sure.
Cons
To be honest, the only thing I consider bad is that they let people demand too much. they ask, they get. The first time they don't get something as fast as they wanted bad reviews start pouring. It's not fair, nor realistic.
