Here are 6 common job-hunting myths, according to staffing firm Robert Half International Inc.

Myth No. 1: You should keep your resume to one page; any longer, and hiring mangers won't read it.

Few employers are so rigid that they'll toss out your resume because it's more than a page long. What's more important is that the document is interesting to read, tailored specifically to the position you are applying for, and error free. In fact, 84 percent of execs polled said it takes just one or two typographical errors on a resume to remove a candidate from consideration for a job opening; 47 percent said a single typo can be the deciding factor.

Myth No. 2: It's pointless to request an interview with a company that isn't hiring.

Even if a company isn't planning to add staff anytime soon, chances are you can land an informational interview. Many employers will be willing to sit down with you if you show genuine interest. An informational interview probably won't result in a job offer, but you will build your professional network and may learn of future opportunities with the firm.

Myth No. 3: If you've applied for a position and haven't heard back, it's safe to assume the position has been filled.

Just because a company hasn't contacted you doesn't mean they aren't interested. It's not uncommon for hiring managers to be so busy they delay contacting candidates for as long as two months after posting an employment ad. Don't let this discourage you; instead take action to see where you stand. Ninety-four percent of executives surveyed said candidates should contact hiring managers after submitting a resume; 82% recommend doing it -- whether by e-mail, a phone call, or personalized letter -- within two weeks of submitting a resume.

Myth No. 4: The most-qualified candidates always get the job.

While employers want to hire professionals capable of doing the job -- and carefully compare candidates' education, skills, and experience against the requirements of the position -- they also depend on intuition when making a decision. Forty-six percent of execs said they rely heavily on instinct when hiring someone. The traits that make an employer want to hire someone often involve soft skills -- like your ability to get along with the rest of the team. Soeven if you don't meet all the job's requirements, don't immediately dismiss it. Your personality may put you on par with someone with more experience than you.

Myth No. 5: There's no room for salary negotiation in today's job market.

Demand for skilled professionals continues to outpace supply in a number of specialties, and candidates with industry experience and expertise often receive multiple offers. Researching how much those with similar qualifications in your area are being paid will help you choose the best opportunity and negotiate a reasonable rate.

Myth No. 6: When times are tough, take the first job offer you get.

An extended job search can put pressure on you to accept any offer that comes your way, but do your best to avoid accepting a position that may cause more heartache than happiness. Tolerating a job you hate -- whether for a week or year -- can set you back professionally and take a toll on your well-being. You may have to accept a "less-than-perfect" role in certain situations, but don't feel guilty holding out for a position with maximum appeal if you have the financial means to do so.
