I applied online. The process took 1 week. I interviewed at EduStaff (UK) (London, England) in June 2018
Interview
Very simple verification questions. Just hand in you certificates, address proof, identity proof etc and explain why you would like to be a teacher or a teaching assistant. Get two references and a DBS check if possible.
Interview questions [1]
Question 1
Why you want to be a teacher for Alevel maths and Physics?
