Prepare beforehand.

• Bring  your resume with you and be prepared to complete an application before or after the interview. 
• Know where you are going plan to leave early.
• Do some online research of the client's industry and determine what is typically expected of people in the role you are interviewing for.

Know what you are talking about.

• Go to the employer's site, or search the web for information such as:

  How big is the company in terms of its competitors by annual sales or employees and what does the company say about its products or services?

  What recent news (such as a new product, a press release, an interview with the CEO) can you discuss? If the company is public, the boilerplate at the bottom of its press releases will tell you a lot.

Be a proponent for yourself.

• Be prepared (memorize if necessary) to relate your recent accomplishments and achievements, as well as how they positively affected your work and the company.
• Wherever possible, quantify what you've done, e.g., "increased sales by 20 percent," "cut customer call waiting time in half," "streamlined delivery so that most customers had their job done in two days."
• Non-work achievement stories are good too, achievement stories make you memorable and allow you to connect in a memorable way.

You have one chance to impress.

• Dress better than suggested — get a good night's rest.
• Be well-spoken and knowledgeable about the position.

Send a simple thank you email.

• We have had candidates not receive offers because of the unprofessionalism and poor grammar used in their thank you note!
• Be short and to the point.
