About MLK, I presume you're referring to this quote:

"We must never substitute a doctrine of Black supremacy for white supremacy"

That's fair, but we're talking about ensuring that the interview process is not discriminatory. I.e. having some extra safeguards for marginalized people (safeguards which are not needed for those in power), a special process that you could maybe define akin to "positive discrimination" vs negative discrimination...

And MLK was totally in favour of that:

"society that has done something special against the Negro for hundreds of years must now do something special for the Negro."

Affirmative action in general does not involve prejudice, although some particular instances of it do.
