I applied online. The process took 2 weeks. I interviewed at HiTutor (London, England) in Aug 2022
Interview
Fairly easy and laid back process. There is training to do before which can be a bit tedious but CS were very supportive throughout. You have to record a demo lesson and they give you feedback.
They will sent an email regarding to your demo lesson schedule via skype both adult and children. Then after that wait for 2-3 days for the email if you passed the demo or not
