The DEI policies were effective, particularly the Diverse Slate Approach. But it's legally risky to continue with it under the current administration since it was a race and gender conscious policy. People can argue as to whether it was "discrimination" but it absolutely was conscious of candidate's protected class.
The diverse slate Approach'd criteria depended on the role. Ther are some roles where Asians are underrepresented so they'd count in that role. For tech, they're not underrepresented so they don't count towards the DSA.
