I got hired at Jimmy John's 3 times. They usually posted ads on Craigslist. You respond to the ad with a resume and a little about yourself. If they respond to you for an interview you pretty much already have the job. The 3 times I went for an interview the manager pretty much tells you about themselves admin about the job and then let's you know when you can start.

There was no formal interview process. I discovered the job on craigslist and showed up to the location mentioned in the ad. The store was still under construction. They had a table outside. Once we finished the interview they said I started next week. Not too difficult, nearly anybody who applies will be accepted.
