FAILING TO CONTROL NERVOUSNESS: The nervous energy that most of us experience during a job interview can lead to very bad habits. Tapping feet, biting nails, poor body language, fidgeting, and a lack of eye contact are all indicators of nervousness. While itâ€™s natural to be nervous, itâ€™s important not to let your nerves get the best of you. Avoid having something in your hands that youâ€™ll tend to play with, be sure to sit upright with good posture, and always maintain good eye contact. Itâ€™s important that youâ€™re able to engage the interviewer and keep his/her attention. The key is to have them focused on how impressive you are, rather than how nervous you seem.
