No, they just don't pass decent selections on to the managers. They pass along the politically correct choices.
They don't know how to screen for competence.
No wonder we are losing our competitive edge in many industries. I am glad I am retired. When I do get a gig to teach an on-line course the college is so obsure or the skill set very specific that I have little competition.
I was chair of the Library Committee at the college I taught at. When a vacancy occurred for a librarian’s position I formed the search committee with three colleagues, a member of the library staff, and two students (seniors with good work ethics and good GPAs).
We advertised in the appropriate journals, library associations and so forth. We might get 100 applicants. All HR did was to place the applications in order in which received. The committee would review each application-50 might be immediately placed in the round file for lack of experience or degree. The remaining 50 were examined and the committe NOT HR would decide to inverview by phone or Zoom 8 to 10 candidates, and the committee would invite 3 or 4 to campus. We would rank the candidates and recommend one to the provost and president who made the final decision (they never rejected our top choice)
HR had no decision in the hiring process. They would schedule each candidate’s visit to campus and schedule meetings with our committee, students, faculty etc.
