I applied online and eventually received an email inviting me to a group interview. The interview was fairly casual. All applicants were taken into the break room where we introduced ourselves, why we wanted the job, and talked about Aldi as a company. We were given a tour around the store and the back storeroom and was told how the store works and what responsibilities the staff have, like stock replenishment (and how incredibly fast you have to be), cashier work, and general tidying and such. Aldi staff do everything in teams of 4-6 in each store, and you need to know how to do everything.
