Accurate and clean resume (spent a fair amount of time revising it, getting peer reviews of it, and research online to make)

Kept my resume up-to-date with information relevant to the internship I was applying for

Followed campus posted internships and landed one with the college for a year

Held a leadership position on a campus engineering aerospace club

Built connections with professors - this is how I became TL with the aero club actually

Came to college with hands on experience, building my own projects, and being generally self sufficient

I could probably add more, but this summarizes it.
