First impressions are formed within the first seven seconds of meeting someone and greatly impact how the rest of the interaction will go. To make a strong positive first impression at a job interview, be sure to arrive 5 minutes early, dress professionally in clean, well-fitting clothes or a suit, and greet the interviewer with a firm, eye-contact handshake that conveys confidence. Checking these boxes for appearance and initial greeting will help ensure the interview gets off to a good start.
