CHEWING GUM, EATING OR DRINKING: While fresh breath is always important, itâ€™s never a good idea to chew gum during an interview. As a matter of fact, you shouldnâ€™t be chewing, eating, or drinking anythingâ€”unless youâ€™re meeting over lunch of course. Though many people like to have a cup of coffee or a bottle of water on them at all times, it really isnâ€™t appropriate to bring these items into a professional interview. Chewing is a not only a distraction, but is considered disrespectful by some. So, finish your beverages and get rid of your gum before going in the interview. If bad breath is a concern, pop a mint and finish it right before the interview.
