ALDI Store Assistant interview questions

Initial small group interview, then had to book an individual interview with the area manager. Fairly standards but I think because of a hiring surge they are very busy because the managerwas extremely rude and dismissive, asking intrusive questions that, I think, were quite discriminatory!! As soon as I entered the room he leaned back, crossed his arms and scowled. Obviously he was fed up with interviews but it was a waste of mine, his and ALDI's time in even bringing me in. Hope it gets flagged with upper management.
