One of my clients was recently invited by a recruiter to become a Friend on Facebook.
This client had hoped to keep her Facebook personal and use LinkedIn for professional contacts.
At the same time, she wanted to develop the relationship with this recruiter and worried that Ignoring the request might be viewed as a rebuff.
In the end, she contacted the recruiter via email to let her know that she wanted to connect via LinkedIn instead.
Score one for boundaries.
Many people keep my client’s online boundary: Facebook for personal; LinkedIn for professional. When I recruited, I deliberately chose LinkedIn for my research and sourcing because I didn’t want to risk crossing that common boundary. It’s the same reason I tried a candidate’s work number first before calling home or cell.
If you would like to keep a personal and professional online boundary, then be consistent. Keep your professional research and inquiries in one network and personal separate.
Realize, however, that not everyone feels this way, so you may have people reach out to you in ways you didn’t intend (as with my client and the recruiter), and you want to deal with these inquiries consistently. You will want to keep your personal networking profile as private as possible if you indeed do not want it used for professional inquiries.
Another consideration is that the line between personal our professional lives is often blurry, especially when we are in job search mode (and who isn’t these days, even if you are employed). You want people to be able to find you. Your friends are most likely to think about you and advocate for you.
