What is the best strategy for preparing for an interview?

Identify the five points that make you the right person for the job. Organize and memorize your five points so you can slip them into the interview conversation at every opportunity.
Finally, be sure to practice delivering these five arguments in 60 seconds or less.
Think of an interview as a 60-second sell, the elevator speech that will capture (or lose) an interviewer.
You want to leave a potential employer with a positive impression -- an impression focused on your five sell points rather than cluttered with details about your work experience or other aspects of your meeting.
