2 mock classes, with very helpful mentors. if you are successful on mock 1 , you get to book the mock 2. and based on the results you get offered a contract and the compensation. after that, you still have to work your way in the free (you get compensated) classes, to be able to teach all the levels.

Interview process was relatively fun and easy if you're comfortable doing part of a mock teaching lesson. They may do it differently now, but that's what I had to do when I interviewed.
