Lidl Sales Assistant interview questions

I applied directly to Lidl, completed an online assessment and was invited to an interview a couple of weeks later. The interview was with the manager of the location I would have been based in and an HR staff member from Lidl HQ. The store manager was dressed very casually, in a t-shirt and jeans, and the HR guy was in a suit. The interview itself was fine, as far as interviews go it was quite relaxed. I was told that someone from the HR team would follow up with me within 2 weeks to let me know if I had been successful or not. I didn't hear from them so in the 3rd week I contacted them and was told that they were still deliberating and someone would be in touch in a week or so. Nobody ever contacted me.
