By establishing a rapport with your interviewer, you build
"common ground" between the both of you. It is important to
listen and be sensitive to the interviewer's style. This can
make communication easier and the whole interview more
comfortable.
Listen closely to the interviewer for cues on how you should
act. Is he being formal or informal? How loudly is he speaking?
What sort of information is he trying to solicit: general,
professional, or personal? Once you've determined where the
interviewer is 'coming from,' you can follow hiher lead.
Try to speak with the same rhythm and tone of voice. Make some
friendly observations about your surroundings. If the interview is
conversational, make small talk about your interests,
hobbies, or what you did last weekend. Be positive and upbeat.
All of these will help both of you relax and establish a
connection.
It's important to appear open and friendly as well. Give the
interviewer a firm handshake if he offers it, and remember
to smile. Make sure you look attentive, with good posture and
consistent eye-contact.
