I applied in-person. The process took 3 days. I interviewed at Kumon (San Francisco, CA) in Aug 2015
Interview
I have taken 3 math exams in 3 hours. The exams covered all levels of math. They are easy for me. That's it, no other questions, very straight forward. If you are confident with your math, you do not have to prepare anything. Otherwise, you need to review math up to calculus.
The overall interview is mainly involved about math knowledge based questions that tested basic concepts, problem solving skills, and understanding of fundamental principles rather than complex calculations or advanced topics.
It was online on Google Meets. They made me introduce myself, my education and my previous experiences with teaching. Then they gave me a few math questions to answer. They also asked me to mock-tutor some math questions.
