Appropriate eye contact throughout the interview is another signal of confidence and professional demeanor. Find the balance between awkwardly staring at the interviewer and looking all over the place.
Casually break your glance when appropriate for brief periods of time, but make your actions appear unforced and natural. When interviewing in front of multiple individuals, shift your glance from person to person, as if you are talking to them individually, but give the most attention to the person who asked you the question.
