Research has shown that tone of voice and body language accounts for 65 per cent of what's communicated, and words account for 35 per cent of the message that's communicated.

Body language can give away a lot of our feelings, regardless of whether we keep our mouths shut or not. And without an awareness of our actions, nervousness, dishonesty, boredom and other negative attributes can become dead give-aways.

Before taking a seat, be mindful of what you'll be staring at. If you have a choice, avoid staring at a bright window. If you don't apparently have a choice, don't be afraid to ask. Ensure that you have room to move and reposition yourself if you become stiff or restless.

To begin with, you need to set yourself up in a confident and comfortable position to help avoid negative body language habits. Make sure you are comfortably seated in an upright position ensuring that no particular part of your body is under strain (e.g. your neck).

Keep your hands rested in your lap, your head raised showing an expression of interest, and relax your shoulders without slumping into the seat.

Body signals
Whether we intend it or not, our body language gives off subtle signs which are subconsciously interpreted by the other party. We likewise read the same into other people's behaviour.

Every little frown or smile gives us the caution or confidence to make our next statement and it is a sublime skill which every human being has developed since childhood.

Some people are more receptive to body language than others, but as a candidate striving to make a good impression, it is important to be aware at all times of the body language that may give out a negative impression.
