I have just found which i thought can be helpful for you:
It was a group interview with 4 stages. I think most of the time they were also watching you to see how you got along with the people surrounding you so if you were quiet that might work against you. So basically we’re sat in 2 rows of about 20-25 people. There’s a panel of 4 John Lewis managers in front and everyone is sitting.
Stage 1: Describe yourself and why you want to work there. You just talk a bit about yourself and make sure you talk about the John Lewis Partnership.
Stage 2: Sell a John Lewis item. They present to you a basket of objects, you get 5 minutes to think of things to say about it to sell to a customer (the panel). If you laugh a bit it’s okay, just talk about textures, situations you could use this item etc.
Stage 3: You’re put in groups. You each get a white board. There’s a sheet of paper with a list of tasks i.e. Answer phone, clean shelves, mop up liquid on floor… And the scenario is that you have a big line of customers, there is a customer complaining etc… and you have to put them in order of priority. You have to make sure you know that you can use all members of your team simultaneously to complete the tasks.
Stage 4: People on a desert island, half of them can be saved, the other half will perish. Choose who gets to be saved. Advice: don’t assume that anyone who is a doctor is good, you can’t judge people on their backgrounds if you don’t know them.
Don’t forget to come back here and let us know about your interview!
Good luck.
