I applied in-person. The process took 2 days. I interviewed at Kumon (San Jose, CA) in Mar 2016
Interview
During the interview, they asked me about my experience working with kids. How i would handle different situations and how I would teach the children. They made me complete an assessment both math and writing. From there, they assessed me and gave me a job offer.
I met with the manager, and they asked me about my previous experience of teaching or working with Kumon. They ask about their vision/mission statement. It's really casual because though it's a big company, each location has only one manager.
You need proof of residence and ID, and must take a timed test covering basic 5th-grade math skills. It's straightforward but requires quick thinking and accurate calculation. I don't recall taking an English test version but they were nice.
