Your body language and gestures play a significant role in communicating confidence, enthusiasm, and professionalism during an interview. Start with a firm handshake and maintain good posture throughout the conversation—sit up straight, keep your shoulders relaxed, and avoid slouching. Make regular eye contact to show engagement and sincerity, but don’t overdo it. Avoid crossing your arms, which can make you appear defensive, and instead, keep your hands in a relaxed, open position or use them subtly to emphasize key points. Nod occasionally to show you’re listening, and smile when appropriate to convey a positive attitude. By being mindful of your non-verbal cues, you can make a great impression even beyond your words.
