I don’t understand your argument. The whole purpose of AI-driven recruitment is to reduce human effort by doing some work for them. If AI due to existing bias reduces diversity in your pool of candidates, what can you do with it? You either do not notice the bias and just think that those people are indeed the best fit, you willingly accept the bias („But it reduces our hiring costs! We deal with diversity later, when this technology matures!“), or you go to see the unfiltered stream and put such an amount of work into it that makes AI useless. HR departments are not the people who will build their own solution, they will buy it from a third party and they won’t have control over or the budget for the fine-tuning.
