I was interviewing a candidate a few years ago for a machinist position, and he had a nice portfolio of past projects he had worked on. The bound folder had drawings (title block blacked out for company privacy) and code examples. It really gave me an idea of what kind of work he was comfortable with, as well as his programming style. Any time you can show a potential employer your code and the drawings of parts you have machined in the past, you will make an impression. So get working on your portfolio of past work and good luck at your next interview !
