Quick and easy in about 3-4 questions. I walked right in and got things started. I was seated in the classroom and it was only the franchise owner that interviewed me.
The interview was extremely short and contained brief questions. Not a lot of them referred to any prior knowledge regarding math or English skills. The most important ones are regarding one's ability to work with children.
I applied online via email and received a reply in a few days for an interview. It was an 1 on 1 interview. There was no test and the interview lasted for 15 minutes.
