Many radio interviews are taped over the phone. The interviewer's voice may seem distant due to technical reasons. Resist the impulse to speak loudly in response.
Make sure you can hear questions clearly. If you're uncomfortable with the volume, say so.
Always make sure you have noted the reporter's name correctly.
Get your point across quickly.
Use note cards so that you have facts at your fingertips.
Begin your answer only when you are sure the question has been fully asked.
Don't provide new information when asked at the end of an interview: "Do you have any additional thoughts?" If necessary, repeat your message.
Men: Sit on the tail of your coat to keep it from wrinkling at the collar. Wear an off-white or colored dress shirt
Women: Consider wearing a conservative dress or suit. Avoid wearing a top that is all red, black or white. Avoid wearing busy necklaces or bracelets, especially earrings or large pins. Use light studio makeup or ask for makeup. Remove name tags, lapel pins and all extraneous items from your jacket pockets.
