Facebook said on Monday, it was testing a feature that would let page administrators create job postings and receive applications from candidates, a move that could pressure LinkedIn's recruiting business. "Based on behavior we've seen on Facebook, where many small businesses post about their job openings on their Page, we're running a test for Page admins to create job postings and receive applications from candidates," a company spokesman said.

LinkedIn makes most of its revenue from job hunters and recruiters who pay a monthly fee to post resumes and connect with people on what's often known as the social network for business.

In October, Facebook launched Marketplace to allow people to buy and sell items locally as the social media network tries new ways to keep its users engaged.
