This was by far the most enjoyable interview I've ever had, and the most enjoyable job overall. It was a group interview at the store for roughly 1-2 hours, made up of a number of different activities like "put together a selection of items that you would use to unwind", "spot what's wrong with this section of the shop floor", etc. And then in between these activities we would be called one by one to have our more traditional one-to-ones. There were snacks put out for everyone, the first task involved us getting to know each other by just walking around and chatting, and we ended the evening by playing a game of 'two truths and a lie' in a big circle, all sat on the floor. The whole process was very comfortable; they wanted you to feel like you were hanging out with some friends. If you have an interview here, there's absolutely no need to be nervous.
