Costco Wholesale interview questions

Well the place seemed as if everyone was uneducated, they did seem comfortable so maybe they just didn't care. Anyways, I was called in and began my interview with the as gen manager and a young manager I believe. She asked me a series of questions about 15-20 questions she was really impressed but normally takes 2-3 interviews. She said we were going to proceed to the next portion or the interview and she asked some more questions about my previous job and what i did. She was really trying to get what Ive known about the company that i worked for before but it landed me the job.
