Today I got a call about a job, interviewed and found out I didn't get it in about an 8-hour span. This shit moves fast.
You know that saying,"it's easier to find a job when you have a job"? Not in Hollywood - or at least not if you're trying to work on a show. Sure, it might help to stay connected to your coworkers, remind people you're looking so they can forward you things, and pay your rent. But honestly, I think that people who aren't committed to anything have a leg up in the job search. They can go in for interviews anytime without having to get time off or find a temp (I have had several calls asking for same-day interviews) and they can start immediately, which is really attractive to employers. For some reason, many TV shows don't know what positions they're going to fill (or, at least, don't get around to filling them) until it's become a pressing problem.
