The interviewer asks you to choose a subject that you are willing to teach and do a short class in front of the person. It's relatively easy and you just need to be correct and clear.
Acudí a una entrevista en HD Education (Londres, Inglaterra)
Entrevista
They'll let you try out a lesson. And they will act as a student to ask you some questions. And make sure you are good at teaching online. Very easy to pass
Basic chat to get to know you, why you are interested in being a tutor, and then ask you to explain a question through drawing a diagram, with follow up question.
