I love that it allows me quick access for jobs, especially during crunch time when you need something fast! The interface isn't always very user friendly if its your first go around with work class - make sure they have someone who knows how things are intended before signing up or else spend some more money getting them set-up right away so there aren’t any issues later down line!! They can be pricey but definitely worth investing into once everything has been setup correctly (I think this usually takes an hour).
It makes finding my next career move super easy as well since all of these sites just update at different times which really helps keep track off what's going where within minutes instead waiting until tomorrow morning like normally would take hours/days sometimes even weeks.
