If you are looking for a job AND you have a background problem AND you're waiting to talk with an employment agency representative, here's how you don't want the conversation to go.
The representative asks, "Okay, so what are you looking for?"
You respond, "Gee I don't know, whaddaya got?"
Well frankly, this isn't how it should proceed for anyone looking. But you have a background snag and even though you may see yourself with your hat in your hand, you should in fact be rather choosy. You need a specific Job Search Objective and the ability to convey it succinctly.
If you take anything, the chances are good you won't like it or invest yourself in succeeding. If so, it won't last. But unlike someone without a background problem, you'll begin again at the back of the line; which is to say, behind those without background baggage. Each time you start over, you have to go through the whole "process" again ... continually at a disadvantage.
Starting and re-starting from scratch is a prescription for not getting anywhere. And how could you with a "whaddaya got" directionless approach to begin with?
Take this to heart: you need a plan and a Job Search Objective because the stakes are higher for you and the entire "process" is made more difficult because of your issue. Someone with a clean background might be able to "wing it" and come out ahead - but not you.
Jettison the "whaddaya got" approach and take yourself and your situation seriously.
