Can't Even Get An INTERVIEW for Internships?

Hey guys, I've recently graduated and currently looking for a job or internship.

The past 3 years, every summer I've applied for internships, but I don't even get a response. I've just been working in manufacturing where my dad works because the pay there for summer is insane.

I'm open to part-time, full-time, contracts, internships...anything that will allow me to gain good experience really.

Any advice? Do I just suck?
