Tesco interview questions

Applied online and answered a series of questions, got a call two days after for an interview. Arrived at the store and told to sign in. Waited 20 minutes for anyone to see me. Group interview with 9 others, Person kept dissapearing for long periods at a time. Asked the group 3 questions, waited again for half an hour. Had 1 2 1 interview, the job I applied for was completely different to what they were offering now. Asked 2 questions in 1 2 1interview. Seemed rushed and disinterested. Told to find my way out. Got lost as place was like a maze. If they offer me a job I will turn it down. If this is the sort of behaviour from senior members of staff I can understand why the store has such a high turnover. This is not the right first impression to give potential employees.
