O que significa a expressão CATCH 22?

-Hey, I heard you were super excited for a job interview that was supposed to happen yesterday. how did that go?

-That went terrible. They said they were fine with young employees because they needed fresh perspectives but they actually couldn't hire people who had under 5 years of experience. But how can that make any sense? How can I have experience if they won't give me a chance to have my first job?

-Yeah. It's a typical catch 22 situation.

Catch 22: a situation where one thing must happen in order to cause another thing to happen, but because the first thing does not happen the second thing cannot happen
