Interviews is a part of your life, so you can start preparing to this from school or university! You can read articles about how to improve your skills at college essay writing services or essay writing service and read some reviews about it at azwritingreviews.com. Also I have one tip for you:
I have a formula called the 3-to-3 equation – three minutes and three key messages.
Based on the topic, develop three brief key messages about your topic and repeat these messages throughout the interview . (Remember, you have a very limited time frame during media interviews – three minutes maximum if live. If taped, you will usually be edited down to the same three minutes.)
Write the three key messages on a small index card and place it where you can see it (out of camera view) so that you can glance at it if you get off message. Use personal examples or analogies to explain your topic. People like to hear about your experiences because it helps them understand your views.
