ALDI Customer Assistant interview questions

Initially completed online questionnaire and situational analysis test to see if I would be suitable for the role. A week or so later I received an email stating I passed that stage, and would need to complete a video interview, where I would talk in front of my camera and answer questions. The video interview has a time limit for each question - there were only 4 questions, and only 30s to answer each one - this was not enough time, in my opinion So a very short interview, and I felt I answered confidently and well, but they did not select me for the next stage unfortunately. When I asked for feedback, they said they couldn't give me personal feedback. So I will never know why I was not selected, or how to improve at another interview.
