I applied online. The process took 1 week. I interviewed at Pareto (Wilmslow, England) in Sept 2016
Interview
One very quick phone interview followed by assessment day.
Assessment day pretty easy. 2 group exercises. One where you must talk yourself out of being thrown off a raft and the other where as a team you must rank items of importance after a plane crash.
A one to one interview and a 3 min presentation.
