In a TV interview, body language matters. So don’t slouch, but lean forward slightly and you will appear more engaging and professional. A bit of animation and hand movement for emphasis is fine – you don’t want to look as if you are awkwardly rooted to the spot – but don’t jiggle about. Get into a comfortable position and stick to it. Try to look steadily at the interviewer, rather than letting your eyes flit around the room while you are trying to think (staring at the ceiling for inspiration is a common fault). If you are being interviewed remotely, keep your eye-line steady, looking into the camera or webcam.
