A good article on the topic of finding unlisted jobs. Our Recruiting and Staffing divisions wanted to add to this article that a very large percent of openings never make it to the job boards, news papers or even a corporations website. Often a recruiter is working on the position discreetly or the employer is looking to fill the position with internal referrals. Working with recruiters and identifying employers you want to work for in your area and submitting your information to them can be a great way to generate some interviews that no one else is getting.

“Job boards are irresistible because they seemingly put everything within easy reach. Unfortunately, the majority of job hunters are competing for the same small pool of jobs and getting turned down.
More than 80% of job openings are actually unlisted, says Steven Rothberg, founder of job website collegerecruiter in Minneapolis. This can be a good opportunity for outside candidates with research and networking skills since most companies will try to promote from within or rely on employee referrals.”
