First you go through the system check and if that goes well you proceed to demo lesson, for which you prepare a beginner and an intermediate lesson. If you are ready you apply for the demo lesson and an interviewer pops up and act as students would. If you are not using the chat box frequently they say so. If you didn't do well they say so and you are allowed to redo the demo class.

Really easy interview, you just need to tell something about yourself and they just check your equipment (headphones, camera, background). After that, you have a demo class that is harder but you get all the material to prepare
