You have to do a short demo class and then answer simple questions about your availability and skills. The interviewer acts as the student in the demo lessons. The lesson topic is provided.
I applied online. I interviewed at First Leap in Apr 2021
Interview
The interview was easy. It was online with one interviewer. I had to do a demo lesson and was given feedback on that. After the interview I had to do a three day training with a group of other new teachers.
Interview questions [1]
Question 1
What teaching experience do you have? What are your computer specs?
2 Part Interview: First, an initial chat over Skype with a recruiter in Beijing. They ask questions about your education, work experience, future plans and why you want to work in China. Basically checking that you're not massivley weird/ugly/insane.
Second Part is a 5 minute demo class that you present over Skype again. Very easy, just sing songs and teach some basic English. At the end I was given a brief evaluation and then told that I was suitable for the job. All future correspondence was done by email.
