I applied through an employee referral. The process took 2 weeks. I interviewed at Costco Wholesale (Issaquah, WA) in Feb 2015
Interview
A forty minute interview, followed by a Microsoft Excel and Ten-key test. It was a fairly basic interview. They often asked for real-life examples. Make sure to prior to the interview, prepare a number of real-life examples. (Ex: When is an example of how you face conflict with a co-worker, how did you deal with it).
