Eye contact is critical in any interview because it helps you connect with the interviewers and shows confidence and respect. Online interviews can make it a bit challenging because when you look at their image on your screen, they don't actually feel you are looking them in the eyes. To help you with that, keep your eyes on your camera when speaking; this way, they feel you're looking at them. Avoid staring, as it can make the situation awkward!
