• Dress in a manner that is professionally appropriate to the position for which you are applying. In almost all cases, this means wearing a suit. It is rarely appropriate to “dress down” for an interview, regardless of company dress code policy. When in doubt, go conservative.
• You should wear a suit to interviews. “Suit” means the works: a matching jacket and pants, dress shirt, tie, coordinating socks and dress shoes. A dark-colored suit with light colored shirt is your best option.
• Your suit should be comfortable and fit you well so that you look and act your best. There is a difference between not yet feeling at ease in a suit and trying to fit into the same suit you wore to your sister’s wedding when you were 15. (In the latter case, it’s time to invest in a new suit!)
• Avoid loud colors and flashy ties.
• Clothing should be neat, clean, and pressed. If you don’t have an iron, either buy one or be prepared to visit the dry-cleaner’s often. Shower or bathe the morning of the interview. Wear deodorant. Don’t wear cologne or aftershave. You don’t want to smell overpowering or worse, cause an allergic reaction.
• Make sure you have fresh breath. Brush your teeth before you leave for the interview, and don’t eat before the interview. Don’t smoke right before an interview.
• Your hair should be neat, clean, and conservative.
