I applied online. The process took 1 day. I interviewed at Chipotle (Canoga Park, CA) in Jul 2015
Interview
Very easy. Looks for the 13 characteristics which you can just google to prepare for the interview. Most Chipotles have candidates go through three interviews with different sets of employees. It's a group hiring process. The manager doesn't have a say if you're hired or not. It's the employees's decision.
Applied online got an email for an interview. First interview was a group interview of about 6 people. Got a second interview talked to two managers and got the job on the spot
I applied online. The process took 1 week. I interviewed at Chipotle (Gurnee, IL) in Feb 2014
Interview
Three stage process. First interview with service manager, then second with general manager or restauranteur. Third interview is with the entire staff. They hire based on their 13 characteristics. If you can make it through the first two interviews, it is almost guaranteed that you will be hired. Questions aren't difficult, they are more or less feeling out your personality and if you will fit in with the team. Act enthusiastic, and ask questions. Be engaged with the interviewers and if you make it to the group interview, just relax and chat with the team.
