I subscribe to the idea that every occurrence of misbehaviour will ultimately turn into its own punishment. If they are not misbehaving by discriminating against older candidates, nothing will happen. If they are mishaving, all you need is patience, and you will see how it will eventually backfire. Furthermore, I really would not want to get hired by people who, in fact, do not want to hire me. I'd prefer them to tell me upfront: In fact we do not like to hire people like you. It will undoubtedly spare me from much worse than just not getting hired.
