The stages of the hiring process are clearly outlined and include plenty of print and video resources to help you be successful in your interview. They explain what they're looking for in a candidate at great length and include teaching demos and examples that illustrate the Magic Ears brand.
I spent two weeks interviewing with Magic Ears, which included an interview and demo lesson, a "training" and demo lesson, and finally, an unpaid trial lesson with a real student. Two days after my trial lesson, I received a Skype call from a Magic Ears representative saying my trial lesson was great and I should have received an email with a service agreement to be completed and returned ASAP. I also received a similar notification in their hiring portal. However, I never received an email with a service agreement. Three days went by, during which time I emailed and messaged Magic Ears on Skype to follow up but received no response. After three days, I finally received an email saying that after reviewing my trial lesson, my teaching was not up to Magic Ears standards. I've been teaching ESL to young children for six years, have a degree in education and a TESOL certificate, and in prepping for my trial I made sure to have all their "bottom lines" down, but they did not offer any feedback as to where my trial lesson could be improved. The email went on to say that I was not hired, and didn't mention anything about an opportunity to teach a second trial lesson which they clearly stated before would be the next step if I did not pass the first trial lesson. Instead, they said I was "full of potential" (gee, thanks for the validation) and could reapply in three months, and in the meantime I could still refer other teachers for a referral bonus.
I'm not sure how they could have changed their mind on the quality of my lesson so drastically in the course of three days, but they ignored my emails asking for more specific feedback and a second trial lesson. That gives me the feeling that I was not rejected based on my trial lesson, but for some other less transparent reason (maybe my persistence in following up annoyed them, or they didn't want to pay me the top rate since I have an education degree and a TESOL). After this experience, I feel very uncomfortable with the fact that this company has copies of my diploma, official transcripts, and teaching certificates.
There are plenty of established online teaching companies who have transparent and professional hiring practices which I would recommend applying for instead.
