River Island interview questions

I applied in September and received an email 2 weeks later asking me to book an interview time. When i got there, there was a lot of other people, about 15 others and we was all in one room and she asked a question and we had to answer one by one. Then, we had to pick a celebrity and go to the shop floor and find an outfit for them to wear on the red carpet then come back and act out being the celebrity and being a sales assistant.
