Hi, had a M & S role play / interview for a Christmas temp Customer Assistant role a few days ago. I got the job and thought I'd write on here in case it helps anyone.
My two interviewers were really nice. The role play isn't anything to worry about. They gave me 5 laminated pieces of paper with all the information on, laid out really easily. There were columns for starters, sides, mains and desserts as well as a sheet with phone numbers of local stores. I have only ever had one interview before which was an informal chat when I was 16 so I was nervous before. My role play scenario was as follows:
A customer came in to the store and she was cooking a vegetarian meal and wanted butternut squash which was sold out at this store. So I offered a pumpkin instead and said it was a good substitute (I wouldn't have known this but I had a sheet in front of me stating good and bad substitutes for the butternut squash). It really was as easy as reading of a piece of paper. Then she said she had her main sorted and someone was allergic to mushrooms. She also wanted a dessert. Since I had all of the information in front of me, I offered her some different starters / sides that did not have the word mushroom in the title. Then I offered the desserts. Obviously didn't offer anything that the customer may be allergic to or dishes that are not in stock. I also mentioned that there was a 3 for 2 offer on which, again, it stated on the sheet and offered to ring local stores.
Maybe I was fortunate and had an easy scenario but all I had to do was be polite, apologise and offer suitable additional products to her main.
After the role play which lasted about 5 minutes, a manager came in to ask me some basic questions like 'why do you want to work here?' and 'have you got any retail / customer service experience?'.
Basically, use your common sense, be polite, apologetic and there is nothing to worry about. Good luck people!
