I applied online and took a qualifying test. I was contacted for an interview. The phone interview took 15 minutes. The person interviewing me was very polite and it was a relatively easy interview.

First you have a phone interview where you get asked some questions about motivation, tutoring experience, organization, etc. Then you have to go in to do a demonstration class where you teach something you are interested in. They give examples like baking a cake, cheese and wine pairing, etc. Something Non-academic. Then you have paid training where you learn the TPR methods.
