I applied online. The process took 1+ week. I interviewed at Delaware North (London, England) in Jun 2016
Interview
It is a group interview process, they test your ability to work in a group and how comfortable you are getting to know new people. They also took you around the stadium and showed you where you might be working and what other locals would most likely look like.
