To make a good impression in an interview or networking situation, it is important to consider how you are perceived from the employer's perspective. Within the first 7 seconds, employers form an impression of applicants based on appearance, attitude, confidence, and approachability. Key things that create a positive perception include being well-groomed, making eye contact, having a firm handshake, displaying enthusiasm and passion for the work, and showing humility rather than arrogance. It is also important to connect with people on a personal level by finding common interests and actively listening.
