Sounds familiar.
One correction I should make: we were recently approved to hire through a fellowship program. While DEIA is a stated goal of this, the fellowship is not exclusively for ethnic minorities. From our larger department that my agency is a component of, about 75% of individuals currently serving that were hired through longstanding fellowship programs are from minorities.
With that said, in my current assignment I have a direct role in the detection and investigation of insider threats. The vast majority of issues we see from the fellowships programs is that they're recruiting exceptionally talented individuals, literally the exact opposite of what everyone fears with diversity hiring by lowering the standards. The problems we see with this is that fellows tend to display higher rates of narcissistic personality disorder, and tend to violate laws and department regulations at a higher rate than personnel hired through the traditional accession pipelines...this is a character trait that transcends ethnic background, so when you sift through the bullshit it's really more of a NPD concern by hiring geniuses which applies equally to all demographics, not a concern about unqualified individuals that can barely write a report and still have gang connections onboarding through lowered standards in the name of diversity.
For a comedic example, see the movie "Real Genius", a docudrama about exceptionally talented fellows with anti-social disorders and NPD that sabotage a project in order to undermine national security for their own interests.
