Superdrug interview questions

I applied online and had a call inviting me for an interview about a week later. The interview was in two parts: shop floor exercise and then a 1:1 interview with the manager. The shop floor exercise involved shadowing a sales assistant and they showed me how to use the till and then let me have a go. The interview lasted about 15-20 minutes with a few typical questions, nothing too difficult. It was friendly and informal.
