If you're applying to that many jobs, you're not being deliberate in the search. I've found all of my post-highschool jobs either from people in my network advertising something, or recruiters reaching out to me.

When I was in highschool I did not understand that it was really about who you know (I was homeschooled, so I didn't have a school network to reach out to for jobs), and went applying for typical highschool retail/fast food jobs willy nilly and never got an offer. It's because I was lacking someone who could "intro" me in to the organization. Now I can't really imagine trying to apply for a job cold.
