LinkedIn overwhelmingly trumps Facebook and Twitter as the social network recruiters use to search for job candidates, with 48 percent using LinkedIn alone, according to a recent study by Bullhorn, Inc.

Facebook is the least-used network by recruiters, although more candidates are looking to use it as a professional tool.

And job recruiters might not be tapping all of Twitter’s potential. The study found that a recruiter’s Twitter followers are three times more likely to apply to a job posting than a LinkedIn connection. See the findings in the infographic below.
