Costco Wholesale interview questions

Received phone call to come in for a phone interview. Arrived for the initial interview aprox. 15 minutes early and was seen right away by the Interviewer. It was a rather stiff and formal introduction with a "soft" handshake from the interviewer. I can't stand that! Aprox. 5-6 questions mostly the "tough"behaviorable ones! Interviewer was friendly and the interview lasted less than 10 minutes
