Sourcing on Facebook is completely different to sourcing on LinkedIn, a Job Board or even your ATS. All those resources rely entirely on what a person says about themselves where as on Facebook you can find people based on entirely on what other people say about them.
In this video I demonstrate how to find people based on who their friend are and what photographs they may happen to be tagged in. With these two techniques I can find people who may have a very low profile anywhere on the internet.
I'm working on a series of Facebook sourcing videos which I am publishing on my YouTube channel and would be delighted to get some feedback on how recruiters are using Facebook to source candidates.
