Started with a phone call with a Dexters recruiter, followed by a meeting with the MD and then a final meeting with the directors of the office they want to place you in.
I applied online. The process took 2 weeks. I interviewed at Dexters (London, England) in Jan 2020
Interview

It is a clever way to get it done and though they don't quite tell you that's what they want, it's clear after you leave.
