Costco Wholesale interview questions

It was 2 hours long ,you have 2 interviews in the same day one with department manager and the 2nd with store manager . They ask about 8 questions it is a group interview

Applied online. Got a phone call 2 days after. We set up an interview for the following week. Very bad experience I was told exactly the following: There is no such thing as a set schedule here we have to stop this right now. Thank you. Very unprofessional. When I applied I was asked for availability and I did so. I dont know why I had a call for interview if there is no such thing as a set schedule.
