Tesco Customee Service Representative interview questions

It was a professional experience in which before the interview I had to complete a series of question (Around 30), and if I answered any incorrectly my application was voided. The actual face to face experience was not as difficult as I feared and was relatively straight forward and friendly.

Interview was short, held in a dingy room above a store. Hiring manager was friendly and engaged but as there was clearly many candidates before and after me to interview, was brief and didn't ask many indepth questions. Did not recieve any response after interview at all, not even a rejection. Very unprofessional as it could be fully automated but they just didn't bother.
