I applied online. The process took 6 days. I interviewed at Sonic (Las Vegas, NV) in Jan 2016
Interview
It was a quick 15 minute interview. He was very closed off but asked normal interview questions. He was extremely nice and tried his hardest to make me comfortable being that it was my first interview. Hired on the spot.
The process was a very simple and friendly interview. Very professional for a fast food chain. Would recommend for a high school student or a recent graduate looking to start making money.
Quick and simple. Simply apply online for the location you want to work in. When they are hiring, they call you back rather quick. Go for the interview and it's easy.
