I applied in-person. I interviewed at Publix (Bluffton, SC) in Dec 2010
Interview
If you want to be hired you need to first fill out an application. Then show your face almost daily bugging the store manager, then you need to make sure that you are available to work at any time they need you, and be willing to work wherever they want to place you at first. Once you get your foot in the door you can submit an ROI (request of interest) what position you would really like to be in.
