Costco Wholesale interview questions

We met in the relaxed resto (cafeteria) area and was asked if i was ok with certain job aspects that was required. Talked about the hours and answered a few simple math questions.

Telephone pre-screener and brief summary of job description and setup time and date for interview and what to bring to interview. Upon arrival connected with membership manager at membership desk per request over phone. Waited about 20 min or more for 2nd connection as she was busy at desk. Finally connected and gave me 4 pg job description of what task I might do and how easy or difficult they might be. About 45 min. later two non-related staff approached me from another dept and said they would be interviewing me. It lasted bout 5-10 min only asked 2-3 questions. I asked for clarification from job analysis doc I read through and got answers back. They said they would be interviewing for 2 weeks more but next day received form letter hand scribbled name and date and unrecognizable signature.
