1.  Prepare a list of questions that an interviewer might ask you.

Don't overprepare or memorize answers because stock answers seem phony and superficial. Be ready with specific, concrete examples to back up your answers.

2.  The best interviews are two-way conversations.

Just as they are interviewing you, you are also interviewing the organization to see if it matches your needs. Be prepared with questions to ask the interviewer, and it is OK to ask questions throughout the interview, though you should save some important questions for the end. A lack of questions on your part may well be interpreted as a lack of interest.

3.  Dress for the part.

Appearance is of utmost importance in an interview, and while this may sound cliche, you never get a second chance to make a first impression. Your interviewer will make a visual impression of you within the first 10 seconds of the interaction, and you don't want your appearance to become an issue. Rather, the interviewer should be focused primarily on you and your ability to do the job. So, be neat, clean, and tidy. Wear clothing that is well-pressed, solid colors, or muted patterns. Always err on the side of conservative dress.
