1. Leaning Back Too Much (Can come off as lazy or arrogant.)
While doing things that help you feel relaxed can be a good way to adjust to a situation that makes you nervous is good, relaxing too much will send the wrong signals. When appropriately relaxed, others will perceive you as confident. If you’re too relaxed, that confidence can seem like arrogance. Be conscious of your body and adjust your posture to be professional but also relaxed.
