What kind of Eye contact at the time of Interview

Looking straight into somebody’s eyes when we are talking tells the person that we are interested, attending to what is being said and have nothing to hide. When we feel shy, it is sometimes awkward to keep this direct gaze on the interviewer. If you find this difficult, at least try to look at the interviewer when he or she is asking you a question, even if you look elsewhere during your response. If you are being interviewed by more than one person, do not always try to include everyone in the panel in your glance. Instead, when one interviewer asks you an individual question, treat that person as though he or she is the only one interviewing you.
You should ensure that your behaviour cannot be perceived as flirtatious. This is not part of any job description and if your behaviour seems inappropriate, it could work against you and you may not be taken seriously as a candidate.
