Obviously, what both the employer and job seeker says is important. How you respond to questions, what stories you tell about your current role, how you describe your relevant accomplishments and how you demonstrate your technical competence are critical to interview success.

However, the impression you make on any employer at an interview is determined by far more than what you say. Your silent, nonverbal communication will be carefully scrutinized and evaluated.

Consider well the following:

Your handshake

Even though President Barack Obama has been known to greet people with a fist bump, you’d best not try that when meeting a potential boss in an interview! Remember that the origin of the handshake was likely to build trust. In ancient times, people demonstrated that they were approaching each other unarmed by walking toward each other with the right arm extended and right hand open. The message was simple and remains the same today: Even if you don’t know me, you can immediately see I can be trusted to come in a spirit of cooperation.

Your body language

body language shows whether you are insecure or self-assured, speaking truthfully, enthusiastic, take your work seriously and more. It is important to walk fully upright with your shoulders squared and with a smile on your face. Neither lean back in your chair, nor bend intently over table in front of you. No matter how nervous you feel, take a deep breath and smile!

Your eye contact

Are you the kind of person who looks someone right in the eye, projecting strength and interest? Or do you tend to look down or through a window away into the distance? Do you point your head away from the person with whom you are speaking? Some people find it incredibly hard to look people straight in the eyes, and if this describes you, you need to practice, practice and practice until you feel more comfortable.

Your poise

As you sit in your chair, do you have that deer-in-the-headlights look on your face? Are your hands shaking, or are beads of sweat rolling down your forehead? Are you shifting your position frequently?

Or do you hold yourself in such a way as to demonstrate a sense of balance and self-control? Your posture and overall bearing demonstrate if you are the kind of person who can handle pressure without showing it. Rare is the job that doesn’t have some amount of stress related to it, and employers continually seek people who will be able to cope with it successfully.

Your believability

Gaining credibility depends on far more than simply demonstrating technical knowledge and competence. Research found that among the traits that help demonstrate believability are composure under pressure, the ability to convey genuine warmth and caring for people and your sociability. All that includes your social skills, etiquette and conversational appropriateness.
