The last job I had I didn't have as much of the training in certain areas as they would have liked (I was a line cook with more experience working with cold food as I'd worked in a deli before) but I survived. I really enjoyed the job, became good at it, and left with a good reputation.
My mother always said you've got to shoot for the stars and go after what you want. I figured it applied even if I wasn't the most qualified person for the job--and played up my other strengths when I interviewed.
