For me it was a role play helping a veggie customer buy an item but it was out of stock. It was suggesting an alternative in that situation and I then tried to cross sell a bottle of wine to them to go with the meal. I was then phoned by the store I was actually applying to work at and they interviewed me too but it was more like a "what hours would you do?" Informal interview. I have been told by colleagues that it differs between when you applied. Some people told me they got interviewed and did the role play at my store, some other people did what I did and had a separate role play and interview.
