Be Self-Confident
High self-esteem and self-confidence are the hallmarks of the successful individual. With confidence, be able to demonstrate how you have overcome obstacles. There’s nothing wrong with feeling good about yourself. Avoid being arrogant.

Come prepared for the key questions
Practice your responses to all the typical questions, such as "tell me about yourself" and "why are you looking for a new position?" How well you speak will have a bigger impact than what you say.  Click here for more information on frequently asked questions read the guideline. 

Remain involved 
The most effective interviews are those where an active two-way conversation takes place. Not the typical question and answer type. Begin early in the interview to interject your own relevant insight. Remember, don’t interrupt your interviewer. Let them finish and then you can talk.

Establish your worth
Discuss your specific accomplishments that demonstrate a proactive attitude. Such as: have you installed systems, done something not required, trained someone, etc. It’s always important to demonstrate how you either created revenue or saved expenses, and be specific with the amounts and how you accomplished that goal.

Know your key strengths
Be prepared to discuss in detail and with examples your five or six main attributes. These should be the ultimate reason you get the job over someone else. Assuming you have done the proper homework on the company, these strengths should also be closely aligned to the key traits the employer is looking for in a person to fill their position.

Give 1 TO 2 minute responses
Communication is the key to successful interviewing. A minimum of one to two minutes of well-prepared discussion gives the interviewer insight into your intellect and supports your contentions.

Provide examples and details
Support statements about yourself with specific examples. These will provide legitimacy to your claims. Without them, the interviewer won’t accept them as valid reason.

Remain attentive
 Maintain good eye contact. Sit forward in your chair. Stay alert during the interview. Show high levels of interest and stay enthused. These actions can maintain or generate momentum during the interview. This is especially important when you are doing multiple interviews on the same day.

Don't be arrogant
A presumptuous, overbearing attitude will offset the finest abilities. There’s a fine line between being too confident and cocky. Don’t cross that line.

Ask probing questions
A few strategic questions can demonstrate your intelligence, analytical skills and assertiveness. Have these prepared from your research. Avoid superficial small talk in your discussion.

Be positive about co-workers
Don’t bad mouth previous positions, companies or employers and your co-workers. No matter how well founded, this implies a negative attitude, typical of those who don’t take personal responsibility for their actions. Definitely a show stopper.
