Prepare well for the range of questions that might be covered. Most questions are likely to focus on your experience, skills and motivation. Persuade your interviewers that you are very motivated to get the job. Tell them about how your strengths and interests match those that the employer is seeking. Answer questions fully but concisely. Speak only about facts that may be of interest to the employer. Be polite, honest and professional. Never lie.
