Most people don’t like watching themselves on tv or listening to their voice on radio. However, if you do an interview, always watch it or listen back to the interview afterwards. You are your best critic so you’ll pick up on any mistakes or annoying habits you see or hear.
Quite often, interviews go so fast that you might forget what you did or said. By watching it or listening afterwards you’ll see areas you need to improve on. This is a great way of improving your interview technique.
