Pros
I didn't stay at Chipotle long, but the people who worked there were very friendly and supportive. They worked hard, worked together, and did their best to have a good time. Starting pay was over minimum wage and there's supposed to be a lot of room for advancement (I didn't stay long enough to see that in action).
Cons
There's a lot of pressure to pursue Chipotle as a career, which I had anticipated slightly through the interview process, but found a bit overwhelming once I started working there. I worked at a store being overhauled by corporate, and the management was abysmal. I was told to show up for training three times, and sent home the first two (after waiting at least a half hour for the manager to show up each time). My "training" consisted of watching videos available to the public on the corporate website about Chipotle's corporate responsibility to food, community, and animals. I was subsequently put on the front line with no training or instructions during a rush and expected to function properly and efficiently with no experience. I have heard that management at that particular store is better now that corporate has left, so I don't think that this is representative of every training experience, but it is something I'd bear in mind were I new to the company.
