I had a group interview with about 12 other people around one large table. I personally found it quite intense as everyone listened to your answers and responses. Also sometimes people would have copied other people's responses.

Group interview of around 15. First task was saying your name a bit about you out loud, just general information it seems like name age what you do. Then the second task was writing down good customer service and bad customer service in your little group and reading it out to the group. During this, they are checking to see what you say, but try not to talk over anyone but definitely stand out. The second task was getting clothes from the shop floor presenting your outfit and explaining your choice. I don’t believe they cared too much about your previous experience but rather your personality.
