Lidl Store Assistant interview questions

My interview process at Lidl was very unprofessional, which was quite disappointing given the fact that I consider Lidl a great company. After an initial application with cover letter, I was tasked to complete an online assessment. Passed the assessment, I had a positive phone interview (about a week later) where I was offered a face to face interview. So far so good, although the lack of flexibility from the recruiter in setting up the interview was very frustrating (only was given one option). I reserved an hour for my interview on the day (due to such short notice, it wasn't easy to take more time off work), which would have been more than enough if the interviewer didn't make me wait nearly 20 minutes in the waiting room during the actual interview.

formal interview process. met in local store and discuss CV, availability, etc. Came in from employee referral so there were not too many difficult questions. did not feel at any time that I was put on the spot.
