Waitrose interview questions

It was group interview with 9 of us. The interviewer was very friendly and told us that whole process will take an hour. First we was playing bingo .We have to communicate as a group and find out who is : -doesn't like red wine. -smocking -speaks Spanish etc. after we have to answer 3 questions: -What is your favourite meal and why? -Why should they hire you? -What is your plans for the future? At the end we was divided into 2 groups and each group get a product that we have to sell to an other group. At the end we told that they will contact us in few days time with results ,i had replay in 6 days .They told that current position is filled in and they will keep my details for the next 3 months and contact me if they have something available.
