I applied online. The process took 1 day. I interviewed at EF (Education First) (Cambridge, MA) in Jan 2016
Interview
It was a phone interview and I was quizzed not on my experience or how I would fit the role, but on whether I'd memorized the job description. The interviewer had very little professionalism over the phone and seemed annoyed that we were conducting the interview at all.
I applied through other source. The process took 2 weeks. I interviewed at EF (Education First) (Zürich) in Jul 2019
Interview
I had a first Skype interview with the manager then two other at the head office. The second one was a group interview and the third one again with the manager and the director.
