Hi BCIguana,
Some highly educated people take starting positions just to get a foot in the door, but it certainly isn’t a requirement. Like you, they’re applying for anything they think they can do.
Aside from “apply for everything”, I’d also suggest that if you see something you’d really like to do — even if you’re not qualified — that you should apply for it as well. Occasionally they may be willing to train newbies.
