Randstad is one of many staffing services I have applied with in the Cincinnati and Dayton areas of Ohio. They are just as bad as all the others: they advertise jobs, rush you into their office to fill out paperwork, sell you on possibilities, and then... nothing. No jobs, no possibilities, just silence. Of course, they'll encourage you to check with them "in case something comes up," and that something will never materialize.
How often can you hear "no" before the hint must be taken?
Don't send them your resume, you are wasting your time. I would go so far as to not recommend any of the staffing agencies in these metro areas, they're all shysters. Apply directly with potential employers; at least if they say no, you're no worse off because you weren't lied to.
