I applied online. The process took 1 day. I interviewed at Engage Education in Jan 2015
Interview
As long as you are not a freak you will get the job. They are crying out for teachers and the agencies also compete for teachers so much so that they fly all around the world. Answer standard questions and you will pass
I interviewed at Engage Education (London, England) in Apr 2019
Interview
I was contacted through LinkedIn and was called for a short interview. There were two interviews and first one was about my background. Second one was to get my hard copies of degrees.
