1. Turn your face fully towards those doing the interview, even if you must move
your chair. Looking sideways can make you uncomfortable. Sideways glances may give the impression of slyness. Your prospective employer can get the wrong idea. 2. Show that you are listening. Be attentive. Make frequent eye contact with everyone in the room as they address you, or by looking at each in turn. 3. Show that you are interested by nodding, smiling, and using appropriate facial expressions.
Interviews are a combination of self-promotion and ingratiation. Try to show your most positive qualities. Find out what the interviewers are looking for and show them that you can offer it.
