An experienced interviewer will watch your body language closely, so be sure to do all you can to avoid signs you are nervous or suggest you might be stretching the truth.
Greetings
First impressions play a defining role in the interview process, so the greeting needs to go smoothly. Make sure your palms are dry prior to shaking hands; moist palms communicate all sorts of messages about an individual – none of them good. A solid handshake is the safest bet.
Sitting down is also less simple than it sounds. Assume a relaxed position, as this will help the interviewer to feel at ease in your company.
Avoid tell-tale signs
Make an effort to keep your hands away from your face. Gestures such as covering your mouth with your hand – something we do subconsciously every day – may be interpreted as nervousness or, worse, dishonesty.
Don't touch your nose. Research at the Chicago Smell and Taste Research Foundation revealed that nasal tissue swells and becomes itchy when a person tells a lie. The interviewer may be on the look out for revealing signs of you scratching your nose.
Eye contact is another factor to consider before stepping into the interview room. Use constant and direct eye contact. There is nothing more annoying for the interviewer than being confronted with a candidate whose is frequently breaking eye contact and looking elsewhere.
To cross or not to cross
Consider what to do with your arms. Do not cross them, as this is an overly defensive posture. Try and find a position in which you feel comfortable. It is fine to be physically expressive with your arms as it can demonstrate confidence in what you are saying.
Equally there are dos and don’ts with your legs. While it is fine to cross your legs, if that is the position you feel most comfortable in, don’t keep crossing and uncrossing them and generally fidgeting, as this will highlight your unease.
Above all try and project a serious and professional image at your interview. Don’t concentrate too much on getting your body language right as this could shift your focus from the actual questions. Finally, don’t be afraid to inject a little humour; it can show you are a confident person with the ability to act coolly when under pressure.
