Costco Wholesale interview questions

Called me in for an interview. There was the front end manager as well as the assistant manager. Few questions were asked in terms of flexibility and your previous customer service experiences.

10 minutes a list of questions they asked everyone. Next day I received an email rejecting me. I interviewed on the second day of interviews for hiring to staff a new store in Wisconsin. How do they know on day two of many hundreds, that they won't need me at their store? This is for part-time work involving great customer service, someone they can depend on to be at work at a scheduled time, take extra shifts when call upon on short notice, but they knew after 10 minutes that I would not be that person. All I can say is good luck. If you pass on a great candidate in 10 minutes good luck in filling and keeping good people.
