I think resistance to algorithms is about failure modes. If an algorithm becomes standard and you are an edge case then you are in trouble, much the same way you are in trouble today with companies that have automated customer support and make it hard to contact a human being. Losing your email account is annoying but not being able to have a job is worse. Automated systems are designed to avoid mistakes but are bad at correcting mistakes. I would argue that even with humans involved the hiring process is harder to some people, even discounting bias, just because it is more or less standard but at least they have hope in the variance that remains.
