Do not ask questions that can be easily answered by a "Yes" or "No".
Most editors will cut out the interviewer's question, using only the answer. If you ask questions that are answered by "yes" or "no"...it does not provide good full soundbites.
Example:
(BAD Question)
"Do you like to surf?"
Answer. "Yes"
Example:
(GOOD Question)
" Can you Describe how you feel when surfing?"
Answer. "Surfing allows me to be at peace with myself, it's the only time I can achieve that".
These are often referred to as "Open ended questions".
I also use a lot of contrast and compare questions...."Can you share how this experience with the product was different then the other?
