I think some basic things like:
Don't get "star struck" when a "quality paper" calls.
LISTEN to the question and answer SLOWLY. Only say things you know for a fact. Not "I think.. it could be... it might have been..."
Take the reporter's name and contact information. If you can record the conversation even better.
Don't be niave (for a non tech article) and think you will get approval prior to publication.
Don't ask for a clipping to show your mum.
Focus on the question.
Remember your company line. Are you authorised to talk to the media?
