I applied in-person. The process took 1 day. I interviewed at Five Guys in Feb 2016
Interview
Standard interview going over experience, company and store policies. Basically they want to know your potential value which has many contributing factors (availability, experience, skills). I was underdressed because I only came in for an application, but I got hired on the spot. They only do online applications now.
Pretty chill' easiest interview ever,
Ask about who you are and what you like always looking staff who can be available all the time, asks why do you want to work there and about availability
Trial shift for 2 hours. Shown around various parts of resturant. Shown how to clean the resturant and how to make the food, focusing on preparing and dressing the burgers.
Interviewer asked me basic questions about myself. She then talked about her experience working in the industry. The interview lasted about 15 minutes and was easy. Basically a get to know you type of interview.
