Get into rapport with the interviewer as quickly as possible. If you are not mimicking each other's body positions naturally, do it consciously. Match the angle of their back and position in the chair. Notice how they are breathing. If they talk quickly, they are probably breathing high in the chest. If they talk slowly, they are probably taking deep breaths. Get into their rhythm for a few minutes. After a while this will become automatic.
Watch while you speak
Be aware not only of your own body language but also the body language of the interviewer. Let their body language signals be your guide as to the level of their interest. Are they bored? Interested? Defensive? In agreement? Disagreement? When you make a point or give an answer, how do they respond? Notice if their body language suddenly changes. Interviewees frequently speak for too long, so be aware if the interviewer starts to nod more rapidly or tap their fingers. They may want to interrupt you.
Show interest
Vary your facial expressions to show enthusiasm and interest. When they speak, lean forwards, nod, or rest your forefinger to your chin to show your full attention. Lower your eyebrows, even frown slightly, to show concentration. Part your lips slightly. Also, make sure you avoid arm barriers when you are listening, as well as when you are speaking.
