What to Do at Your First Job Interview . . . and Not Do: A Guide for Recent Grads.
Here is advice from James Challenger, who is a partner in a job-search counseling organization. He wrote Job-Hunting Success for Mid-Career Professionals.
This advice is for entry-level job applicants.
Don't ask about salary & benefits. Let the interviewer bring this up
Schedule you're fall-back choices first. You need practice. Get it with the future also-rans.
Use your contacts to line up interviews. Who you know counts for a lot. So do people they know.
Don't assume that your first employer will be your only employer, any more than he expects you to stick with him forever.
Don't show initiative. Nobody likes to hire an entry-level know-it-all. Know something about the company, but don't lead with this information in the interview.
Say yes, often.
Follow up by letter. Thank the interviewer. Sound enthusiastic.
Smile.
