It depends on a lot of things. Some people have no trouble getting a job. I didn't get my first real (min wage, part-time) job until after I'd applied at several hundred places. Until then, the only jobs I managed to get were paper routes and temp jobs through a temp agency (jobs that would take anyone for a day or a few days). So ... 30 doesn't seem like a lot to me, but it will seem huge to people who are used to getting one after two or three applications. I got about one interview for every 40 applications I dropped off. I'm an ugly, awkward weirdo, though, with only a hs diploma, and had no credible work experience or references at the time.
I love Society. It is entirely composed now of beautiful idiots and brilliant lunatics. Just what Society should be.
