Spray and pray baby. Getting the recruiter or HR department to like you only gets you in the door. You can't shortcut actual connections with your actual coworkers.
Right. When I was interviewing people, I honestly couldn't care less about the CV. I'm an engineer, words are hard. I want a list of your skills, your software proficiencies, and a run-down of your previous jobs along with your responsibilities. When you get here, I'm going to care about finding out how much you know about designing and cad. Then we'll take a tour of the shop to see if the machinery we build is in your comfort zone. We'll have some small talk to get a feel for if you'd fit in with the group, and off you'll go. All said and done, it should be under 45 minutes.
