Pretty simple interview. No need for preperation. They ask you to introduce yourself and talk about your teaching experience. Where did you hear of them etc. My interviewer was a Vietnameese person with decent English abd she was very friendly. After I answer the questions she carried on with a presentation on the company, recruitment process, hourly rates etc.

It's quite fast, flexible, and supportive. I was provided with all the teaching materials for the demo. The detailed training process and transparent contracts with terms and conditions. Quite good choice for those who are interested in teaching English to adults.
