All you need to get a job is a nice tool box and an lot of confidence. I've seen perfectly good mechanics get replaced by somebody with a fancy ass SnapOn toolbox and a lot of talk about how good they are. Shortly thereafter its realized that they don't know shit, except how to rack up debt on the tool truck.
Tools and real world experiaence are what get you into the door. A degree helps but also normally means the person is overly confident and is going to struggle like crazy for the first year or two. I've seen it first hand. We've got a kid at our shop now, great kid and he definitely has a lot of knowledge (especially with newer computer controlled diesels and EGR systems, most of my knowledge is based on older mechanically injected engines). The problem though is the school taught him to overthink shit and he constantly skirts the real issue trying to find the problem with a vehicle.
