<p>I just applied for three different jobs on campus online, and I'm wondering if I should make follow-up phone calls. They didn't leave an email address, so I can't email the hiring manager...I just didn't know if applying for campus jobs works differently than for regular jobs. I don't know if they'd be annoyed at me calling just to check on the status of an application, or if they would see that as determination or enthusiasm or something like that. Also, what should I say? </p>
