I recently met with a new client and discovered that she is not on LinkedIn. I must admit..I am amazed. LinkedIn is one very powerful source of information for any job seeker. If you must have one online presence only in your job search, then LinkedIn it is...and the reasons are numerous.
If you do not know what LinkedIn is, or how to get started, take the time to figure it out to consult a career coach who will guide you through it. It is worth the effort.
