I would highly recommend that you update your LinkedIn account if you are looking for employment.
I would start by making sure you have a professional photo attached to your personal profile.
You should populate the experience sections with your resume but feel free to use a more conversational tone and describe key projects that you’ve worked on
LinkedIn is a wonderful tool for this type of professional networking, while Facebook seems to be more for personal relationships.
My recommendation would be not to use Facebook as a tool for job search. Facebook is more of a social site vs. a site for job search.
I use Linked In every single day to find not only qualified candidates for my open positions but also to post jobs, read and participate in discussions and search for other important hiring trends.
I would also encourage you to obtain recommendations.
When thinking about the best point of contact to make within organizations through LinkedIn, I actually recommend peer-to-peer networking.
