When developing recruitment strategy, talent acquisition professionals stress the need to distinguish between passive candidates—typically defined as being employed and not looking for a new job—and active job seekers.
But does it really matter where the qualified leads come from or whether or not they're employed? The goal is to fill open jobs with qualified people, whether a sourcer found them at another company or they actively sought out their dream job. Any recruitment strategy, therefore, must appeal to a wide gamut of candidates with varying levels of interest in a new position.
