Group interview, followed by a solo interview. tested on teamwork, public speaking and repetitive tasks. observed by managers, supervisors etc. not much else to say about the whole process to be honest

First was the assessment day, in which we all sat in groups, completed fun tasks like making up a poem about the diner, and seeing who can make the most paper hats. A few questions were asked. It was a very fun assessment day! It lasted about 3 hours. Next was the interview stage. Very simple, they simply asked about your CV, such as any employment gaps, previous jobs etc. I was told I would receive a phonecall within a few days. Whole process took a couple of weeks, and was one of the most enjoyable interviews I've had.
