Mechanical engineering internships are won on three things: hands-on project work that demonstrates the CAD and analysis skills your hiring manager actually uses, a resume that surfaces those things in the first six seconds, and the right keywords from the JD so the ATS doesn't filter you out before a human sees it.
This page is a working playbook for that. The before-and-afters below are the most common weak bullets we see from juniors and seniors applying to SpaceX, Tesla, Ford, GM, Boeing, Lockheed, and the manufacturing rotational programs (P&G, GE, Honeywell). The keywords recruiters at those companies actually grep for. The ATS traps that quietly kill resumes from students who built real things. And a free tailoring tool that turns your existing resume into the JD-specific version, in about two minutes.
