If you want this job, prepare well! I have no idea how many hours I spent of prep. Likely over 20. Initially, you apply and if you have teaching experience and a Bachelor's degree you proceed to next level. You can either do a demo video or teach a demo class to a team member in Beijing. (I went with the video). You will get feedback on the video, and if you pass you move on to the Mock Class stage During Mock 1 you teach 15 minutes of a lower level class to a mentor and receive feedback. Then, in the same video call you will teach 10 minutes of an upper level class, and get feedback. Many (most from what I understand) then receive feedback and have to teach another Mock class (Mock 2). I was offered the position about 10 minutes via email after my Mock 1 class, so cannot speak to what Mock 2 is like from experience. It is an incredibly extensive and challenging process. But the process itself prepares one for the job. I can't wait to get started!
