Interview is pretty basic, asking questions like who you are, why you want to work for Costco, describing situations from past work experiences and how you handled them. Dress up nicely, look sharp, talk well and you'll be able to set a good impression immediately.

Applied online, got a call about 10 days later. This was a phone screen, the manager went over the position, answered a few of my questions, I told them I was interested. He scheduled my next interview, in person with a manager and SUP. That interview was pretty easy. Asked some behavioral CS questions, why Costco. Moved me to a 3rd interview a few days later. Met with the AGM. He only asked me two questions, both were questions from prior interview. Hired me, did drug test that same day. 2 days later they called me for Orientation the next day.
