You do not understand how HR works then. They are not LLM researchers and just apply the available toolkit, e.g. organizing regular training for hiring managers. When they buy AI-driven solution from a third party, they have no tools neither to detect if it’s just a statistical fluctuation or there’s a bias they need to find a workaround for, nor to act on this information in a cost-efficient way. Most likely they won‘t even have enough data to reach any statistical significance. The vendor in theory could do it, but most of them are startups now and they do not have diversity in their OKRs, at least not now. It’s not the UVP of their product.
