Your handshake is another crucial part of the interview. It is a form of non-verbal communication and conveys messages to the interviewer about you. It is also important in building a relationship with the interviewer. Consciously try to communicate to the interviewer that you are glad to meet them, through your handshake. Use your face, eyes and body at the same time, to convey the same message. This creates congruence in your body. A weak or limp handshake may give an impression of uncertainty or a lack of confidence.
Your body language provides a number of messages to interviewers. Be confident. When you greet the interviewer smile and give a confident and welcoming handshake.
Wait until you are offered a chair before sitting. Keep your gestures, body and face open.
Lean forward slightly to give the appearance of confidence and interest. Position yourself so that you are sitting right back into the chair, so that your lower-back is fully supported. Relax your shoulders and upper torso.
Maintain appropriate eye contact throughout the interview. (Do not stare or look away too much. Look at them).
Listen to what the interviewer is telling you about the organization and your likely role within it, use appropriate listing cues such as nodding, saying aha etc. Try to look interested at all times.
