About 80 percent of new jobs or job openings in the United States are not advertised. Instead, they come through referrals, localized job pools or other places. This is because most employers don't want to go through the sometimes thousands of unqualified applicants who apply for open job listings. Despite this, Americans spend about two-thirds of their job search time looking at ads, placing ads or sending out applications — and only about 9 percent of their job search time contacting friends and relatives to ask about job openings.
