Arriving at the Interview

Show up 20 minutes before your interview to give yourself time to mentally prepare.
In many cases this could be the first time you arrive to the company conducting the interview. This means you are not familiar with the parking/traffic and exact location to meet. The last thing you want is to be running late and feeling distressed moments before the possibility of this interview potentially being the best career in your path.

Research

Always be prepared for any situation. Interviews are planned ahead which gives you time to organize your thoughts. This includes familiarizing yourself with the company and reading reviews. If you are willing to devote time into your next position, researching the company you are interested in is imperative.

Confidence

The way you carry yourself has a lot to do with how the interviewer reads your personality.
Being overly confident can portray arrogance. You have to put yourself in the interviewer’s perspective. Most companies are not only looking for a technical match, but also for someone that works well with the existing team.

Honesty

The best thing to do is to be honest. When coming across a question that you are unable to answer, let the interviewer know. If you have run into a similar situation in your past positions, you may want to mention that experience. Never let one bad answer discourage you as you carry on throughout your interview. You do not want to lose focus over an obstacle that can be overcome by doing well on the rest the interview. Sometimes interviewers want to gauge how a candidate deals with stressful situations.
