The "nice" Agency recruiters told me on one occasion in 1982 that, given my (academic) background and interests, I likely would be receiving an offer of employment.  On that occasion contact was initiated by the Agency NOT ME!
In 1990, another recruiter assured me that he would be happy to "sponsor" me for Agency employment.  He assured me that my have previously been declined for the Agency intern program in 1979 would  not be an barrier to Agency employment.
What permanently f*cked up my prospects for Agency employment for life was the BI for the internship program in 1979.  I had the luck to have the investigators latch onto various undesirables and incompetents who were willing to spew the most vile garbage about myself.
Yes, if you've been once refused employment by the f*cking Agency, you've missed your boat entirely.  Don't bother wasting your time and efforts, like I did. >:(
