Entry-Level Public Relations?

The elusive entry-level PR position; hard to even find posted by companies and when they actually are, they’re even harder to score an interview for. These past couple months of job searching on my part have left me at times doubtful and a little depressed, and at other times mildly irritated. The responses I have gotten from these so-called “entry level” positions (or lack there of) make me wonder if they actually even exist or if my cover letters are hopelessly floating around in the cyber abyss.
