I applied online. The process took 4 weeks. I interviewed at Sonic (Internet and Phone) (Santa Rosa, CA) in Nov 2015
Interview
Please note, the hiring process is a bit different now compared to when I applied as the Human Resources and Hiring teams have grown quite a bit.
I got a call about two weeks after I applied. They asked me in for an interview the next week, and asked me in for another the following week. I had a job offer about three days after the second interview. The whole process took about a month.
First interview was with two managers, the second was with a manager and the Director of Customer Support. Both were pretty straight-forward, really just feeling me out as a person to see how I interact with others.
