I guess I'm going to be the dissenting opinion here, but don't do it. Sure the experience of interviewing is good, but what if you get the job? I've seen too many young cooks move up too fast. They end up shooting themselves in the foot, in the long run. They don't have enough experience to be a great leader and even less to become a great, or even good, chef, but once you start taking the better money, it's a hell of a lot harder to go back to being just a cook, and so these people continue on. They end up being, at the best, okay chefs at okay restaurants but very few of them have I seen excell. My two cents; take your time, learn all you can from this chef that has taken you under his wing, then go and find another cooking job and do it again. Work for great chefs (and that doesn't mean "big name" chefs) and learn all you can from them. Learn what they do that makes them great, in your eyes and in 3, 4, or 5 years then you will have many (not all) of the skills you will need to be a good "second in command."
