A new survey has shed light on a major inefficiency in the way most people look for a job: Getting referrals.

It turns out that 71% of hiring managers say employee referrals are their best source for finding job candidates, but only 7% of job seekers say asking for referrals is part of their strategy for getting a new job.

The survey, conducted by Beyond.com, a career content and job site, and Future Workplace, a research firm, also found that "passive" job seekers, or those who are employed but open to new opportunities, have a better chance of being hired over "active" job seekers, or those who are unemployed and searching for work.

Hiring managers really like passive job seekers according to the survey, with 80% of HR professionals saying they become the most effective employees. (The survey is based on a national sample of 4,347 job seekers, as well as 129 human resource professionals.)

So what does all of this mean for you if you're interested in finding a new position?

"A strong application coupled with quality referrals will provide job seekers with an advantage in the hiring process," Rich Milgram, CEO of Beyond.com said in a statement. "You should constantly be exploring new ways to nurture and expand your referral network, and it may be easier than you think. For example, attend industry conferences and events, grab lunch with a former colleague or make new connections on social platforms — a few simple actions may help you land your dream job."

Some of those actions, based on highlights from the survey, include.

1. If You're Still in School, Review Your Major

Fourteen percent of seekers surveyed were liberal arts majors, yet only 2% of companies are actively recruiting those majors. And while 30% of companies are actively recruiting engineering and computer information systems majors, just 15% of job seekers are studying in those fields. About a third of job seekers would, or have, changed their college major for better job prospects.

2. Focus on Cultural Fit Over GPA

While job seekers (23%) and employers (24%) agreed that internship experience carries the most weight for students when seeking jobs, employers don't view GPA as carrying a lot of weight (6%) as much as job seekers (12%). Companies put more emphasis on cultural fit (24%) than job seekers do (15%) when recruiting.

3. Be Flexible

Effective communication skills are at the top of the skills list for both employers and employees. After communication skills, employers look for employees with the ability to adapt to change and make sense of ambiguity, followed by being results driven and goal-oriented. After communication skills, employees report leadership ability, in-person collaboration and teamwork skills as their subsequent strengths.
