Online questionare to be completed followed by an email for group interview. Arrive for the group interview along with about 20 others. We spent the day doing group exercises such as mock-selling items to the interviewers and doing role-plays of what to do in given random scenarios such as a customer not being able to find what they are looking for, or one stealing something from the shop etc. I was then emailed and told to come for a second interview. The 2nd was a one-on-one interview discussing your hobbies, examples of scenarios in which you've given good customer service, values you believe are most important about being an employee at Waitrose and other general things along those lines.

It was a group interview/assessment where we were given scenarios and watched as we discussed approaches to take (they value hearing out of the box/pragmatic thinking and watch how you interact and listen to others), followed by short one on one interview with the typical why work for us etc and discussion about the group task.
