> Your HR department needs avenues to sift through referrals and comparison points. If an individual has the certificate and compares equally with a non-certificate candidate, the first individual has signaled, through the certificate, that he is interested in the field, as well as willing to invest time and resources into advancing in that field. This is the flipside of the employee signalling. The real root of the issue here is that HR can't do their job. An unintended side effect of all this signalling is that future employees will be glad to get filtered out because they don't want to work somewhere that hired on certification instead of competence.
