Are you talking about doc-review jobs? Those are basically placeholder jobs that allow you to earn money. They do not develop any useful skills. Doc review is basically just clicking "responsive" and "non responsive" as random emails and corporate document pop up on your screen. Any high-school graduate could do it. It won't kill your career to do it for a very short term, but keep hustling for something substantive. Someone who's been a doc reviewer for too long will become less marketable.
