I applied in-person. The process took 2 days. I interviewed at Jimmy John's (Bolingbrook, IL) in Mar 2015
Interview
No true interview. Asks for availability. They will call you down to the store. They will ask you to take a copy of their menu home to study. They usually give you up to 2 days to memorize as much of the menu as possible. Depending on how you, will determine if, and how soon you'll get hired.
