Costco Wholesale interview questions

I had an interview with both DM and store manager. They are both nice and just ask about what I did with my previous job. What is the average prescriptions filled per week at my store. How do I handle a tough customer?

I applied online and received callback the following week. The initial Interview took place in the Costco warehouse. The interviewer asked me about customer service and job related questions, including the past work experience.
