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.
The best things in life are free, but so are the worst things. And you need money to avoid those.
