whats the deal?

I am kind of pissy today. I recieved another email from some HR puke asking if the amount they wanted to pay me good enough. I had eagerly accepted many offers like this. Then I get no response back to want to hire me.

What's the deal? I am guessing that I am under qualified for some jobs and over qualified for others. But even if I am over qualified and I sent you my resume and you liked it, wouldn't you still hire me? I am getting sick of this shit. I want a job and need to work. Any insight to this would be greatly appreciated.
