I interviewed online, they called me back almost immediately 2 days after asking me to come in the very next day. Since the costco I applied for was not built yet, I had the interview at the local mall. I heard others have a hard time finding the location, but was not hard for me. When I got there, there were 2 others and by the time I was called in the waiting area was quite crowded and had lots of different people there. The girl I sat next to said she was there for her third interview- and that made me nervous than i already was. Little did I know you needed to complete 4 interviews before even being offered a position.(they told me this at the end of the interview.) Two men asked me various questions, which were very situational. You could tell they were looking for very specific characteristics and if you didn't meet them they got you out quickly.
