Show that you take the interview seriously. Your personal grooming and cleanliness should be impeccable.

know how long it takes to get there, park, find a rest room to freshen up, etc.

10 minutes prior to the interview start time (or earlier if the event or employer instructs you to do so).

Treat other people you encounter with courtesy and respect. Their opinions of you might be solicited during hiring decisions.

Make eye contact, and have a friendly expression when you are greeted by your interviewer.

That you understand your interviewer's name and the correct pronunciation.

Even when your interviewer gives you a first and last name, address your interviewer by title (Ms., Mr., Dr.) and last name, until invited to do otherwise.

Maintain good eye contact during the interview.

Respond to questions and back up your statements about yourself with specific examples whenever possible.

The interviewer is evaluating you as a potential co-worker. Behave like someone you would want to work with.

Don't make negative comments about previous employers or professors (or others).

Don't ask about salary and benefits issues until the subject is brought up by your interviewer.

As if you are just shopping around or doing the interview for practice.

Don't act as though you would take any job or are desperate for employment.

Don't go to extremes with your posture; don't slouch, and don't sit rigidly on the edge of your chair.

Don't allow your cell phone to sound during the interview. (If it does, apologize quickly and ignore it.)

Don't take your parents, your pet (an assistance animal is not a pet in this circumstance), spouse, fiance, friends or enemies to an interview.

Take responsibility for your decisions and your actions.

A job search can be hard work and involve frustrations; don't exhibit frustrations or a negative attitude in an interview.

You may not be asked all of them in every interview, but being unprepared will not help you.
