We're Living in a 2-5 Years Experience World, but I am an Entry-Level Girl

Each time I apply for a job I copy and paste the wanted description into a Word document and save the information for future reference. As I was looking over the descriptions today I realized I have applied to a lot of jobs I'm simply not qualified for. In fact, of the 23 positions I am waiting to hear back on, only 10 are at my level of experience. I was so eager to apply to as many positions as possible that I didn't really heed the employers' qualification requirements. It's the old Catch 22. The majority of companies I applied to want someone with experience, but how can I get experience if no one wants to hire me? It's frustrating because I know I could do the jobs I applied for, but I don't have the 2-5 years of related experience. Of the 10 positions I am qualified for, 3 are approaching the two week mark and another the three week mark, so even those applications aren't attracting much interest. I guess that makes my interview with the ad agency all the more important. It's scheduled for next Tuesday at 2 p.m. Wish me luck!
