I am on the other end of this. As an employer, job boards are now essentially useless. Worst of all, we pay per profile engaged. In order for us to verify that the profile is even tangentially a match, we have to engage, but the new algorithms are only providing poor matches. It used to be that we would pay per posting and we could engage with every profile that responded AND every profile that matched our keywords, at no extra costs (this shit costs over $10k per year).
The market is ripe for a competitor that offers services equivalent to what we had nearly twenty years ago.
