I applied online. The process took 1+ week. I interviewed at Spell Languages (Geneva) in May 2017
Interview
Classic letter of motivation and one interview. Many questions on what I would do in the field. Casual staff and engaging atmosphere. They wanted to know my languages skills. It was a comfortable interview and they evaluated how I interacted with kids.
Interview questions [1]
Question 1
what would you do if a kid keeps crying? What would you do when one kid doesn't listen to you and other kids are watching?
