I applied in-person. The process took 1 day. I interviewed at Sprouts Farmers Market (Riverside, CA) in Feb 2015
Interview
There were only a couple of people there and you just had to show up to get interviewed they didn't filter through applicants beforehand. I did a one on one interview with the manager and she just explained the duties of the job and asked why I wanted to work there as well as strengths and weaknesses.
