I would think, and I'm speculating here, that the idea is that the kind of ads they have, justify a high CPC, precisely because you only go there when you're looking to hop jobs. Fewer people clicking that ad out of curiousity, with no possibility of applying for the position posted. $5 CPC makes sense if it gets you a new employee, since (even if it's only 1% of those clicking who you hire) that is a small part of total cost of employee acquisition. I have no idea if this is actually the strategy, or if this is actually working, I'm just floating it as a possibility. You only go there if you're a recruiter, or thinking about getting new work, or you have been asked by somebody else to endorse, and that would be a good thing, in this scenario, since it improves the signal-to-noise ratio.
