When the interviewer finally does arrive, it's showtime. If you appear shy or intimidated, an interviewer may not want to dig too deep and embarrass you; that said, she will not ask you the really difficult questions—the questions that get you the job.
It's human nature to judge a person by their first impression—it's that first impression that hooks many of us when we fall in love. You and your interviewer do not need to fall in love, but you do need to fall “in like.” It shouldn't be difficult to do this, as long as you know what it is the interviewer is looking for.
Maintain Eye Contact
When the time for your interview finally arrives and you get the chance to meet the person who will be grilling you for the next hour or so, stand up and greet him with a warm smile, and maintain constant eye contact during your articulate introduction.
Establishing eye contact is probably one of the most important parts of your introduction. You want to make sure that you look the interviewer directly in the eye as you are being introduced and/or shaking hands. At the same time, you don't want to make him uncomfortable, so be sure not to stare.
Similar limitations are placed on the handshake; while you don't want your handshake to be so light that the interviewer is forced to check for a pulse, you also don't want to be so enthusiastic that she winds up in the emergency room with a fracture. In your pre-interview sessions with a friend, practice your handshake so that you will be able to offer up a firm grip with a quick shake or two of the hand. Then, don't hold on for dear life; let go.
