I applied in-person. The process took 5 days. I interviewed at Walmart (Richmond, KY)
Interview
I applied in-store and was interviewed within the week. I was interviewed by the hiring manager and the manager of the department. They really needed more cashiers so I was told my interview was a formality.
Essentially expect to wait a long time. Like 45 minutes to an hour to be called. They'll probably give you 3 interviews. Ask you the same questions. If you're lucky they'll tell you to come back in a couple days. Then they'll set up the drug test thing, and get back to you in a couple weeks.
