Find a JobThis just in…according to folks at TheLadders, 50 percent of available jobs at the manager, vice president and C-level continue to not be posted online.

This means, of course, companies and their external recruiters, don’t even need to advertise these highly coveted positions and in turn, job seekers without a foot in the door are being left out. Their research culminated in creating a free service called “Inside Leads” which leverages algorithms from recruiters’ online search behaviors. In turn, roles are shared with job seekers in weekly emails. It sounds like each lead will be highlighted to give job seekers the opportunity to apply for the job.

While that’s all fine and dandy, we can’t rely on emails for a passive job search. You probably already know this but it’s worth repeating — considering half of these jobs aren’t even posted for the public to pursue, the weight of networking and expanding your connections is even that more important.
