How's your handshaking skills? If you have never noticed how you shake hands, make a conscience effort next time--it could mean landing that job you've always wanted.

According to University of Iowa business professor Greg Stewart, a firm, solid handshake is important for a successful job interview. The reason is because your handshake gives interviewers their overall impression of you.

Those who scored high on handshaking skills were seen as more hireable. Those whose handshakes were weak and limp were seen to have less of a personality and were less impressive to interviewers.

So, the next time you shake someone's hand, think about how your handshake is matching up--is it firm or is it weak. It could mean that next big promotion.
