You apply online. They’ll phone you in to arrange an interview. It’s an assessment centre, usually 6 people sitting next to each others and a few representatives in the room (team leaders, HR, etc). First take consist on 3 scenarios, you’ll discuss as a group how to act. The answers are working through your break, tell your friend to sign up for the newsletter for his 10% off birthday gift, etc. When you do your word exercises you need to pay attention to punctuation. They will also make you sign up online for which shift you applied for and any pre booked holidays. If you put down any holidays you won’t get the job, which was my case. What happens is, they’ll make you wait in the canteen and come forward for a 1:1 interview... and in the meantime they’ll wait for the results to come on screen about that little part you disclosed online and then invite you out saying they’ll call you soon. They won’t.
