ALDI Sales Associate Cashier interview questions

Was invited along to a group interview after applying online and filling out an exhausted application form. No other candidates showed up for the interview so I was taken 1 to 1. After the interview I was given a maths test. After passing this stage I was invited along to an introductory shift to see how I behaved in a work setting. I was told afterwards that there wasn't actually a position to fill and had to wait several months of receiving pointless emails asking if I was still interested in the job, in May I told them not to contact me again.
