I applied in-person. The process took 2 days. I interviewed at Taco Bell (Sylvania, OH) in Feb 2013
Interview
The interview process went really well I communicated my future goals and impressed the GM conducting the interview. Most of the questions were general commonsense questions, what to do about a belligerent customer, experience in food industry, etc.
I applied online. I interviewed at Taco Bell (Bothell, WA)
Interview
They called me first and asked if I'm able to work overight and then schedule an interview.
They really need someone to work overnight and the manager only asked 2 very simple questions.
I answered a few basic questions and got offered the job almost immediately. I would say dress business casual for the job interview and ask a few questions back to the interviewer.
