ALDI Assistant Store interview questions

Applied on line took about an hour with tests , then was successful and invited to do an online video interview where they gave 30 seconds to answer questions, next was invited to a phone interview with Area Manager, asked about my previous experience and what I would find challenging about working for Aldi, 2 days later received email for invite to store experience, this lasted 2 hours , during which I had to do an "initiative test" moving boxes from 1 Pallet to another and at speed, for someone new to this I found quite hard, im sure after training and getting used to weights of boxes it would be easy, unfortunately I've pulled my back out and now suffering due to this, although health and safety was explained the boxes were actually heavier than I imagined and using muscles I don't usually use, I was told by manager that the area manager would be in touch after he sent my questionnaire scoring me.. 3 days later im Still waiting to hear, , funny really as was told they were desperate for staff and only 2 of us went for the experience day..
