it was simple but busy. Did health and safety worksheet. There are little tests they give you like a maths test about how much change you should give etc, also you have a sheet with a bunch of items and you have to find the code for the items, write them down and get as many as you can in a time limit. The main thing was i was with a supervisor who i went into store and unpacked pallets of stock with him. They are timed but as long as you feel confident there shouldnt be much of an issue. try not to wear anything warm, i was sweating in my coat. I heard back later that day and was offered the job
