It was a short individual interview with a single member of staff, very similar to other interviews of the same industry, very straight forward with simple open ended questions. The whole process took under half an hour.

We were sat in a room of around 15 people. Around 4 employees watching us from the sides, and one employee leading the interview. They had us first introduce ourselves to the group, and then had us get together in small teams and do little exercises, just silly stuff, such as making a house out of spaghetti and marshmallows. Silly tasks, but what they're watching is how you interact with people. They then showed us a bunch of videos of higher ups talking about ASDA and what they stand for. It was an easy going, welcoming experience. Everyone who was normal got hired.
