Put yourself on their team. Ally yourself with the prospective employer by using the employer's name and products or services. Show that you are thinking like a member of the team and will fit in with the existing environment. Be careful though not to say anything that would offend or be taken negatively. Your research will help you in this area.
Image is often as important as content.
What you look like and how you say something are just as important as what you say. The types of questions you ask and the way you ask them can make a tremendous impression on the interviewer. Good questions require advance preparation. Just as you plan how you would answer an interviewer's questions, write out specific questions you want to ask. Then look for opportunities to ask them during the interview.
