If you are invited on a show and the interviewer sends you notes to read.Please read them.  If they have sent  some material to help you prepare please look at. A lot of work goes on in the background and it really helps if you are prepared. 

You may have done a number of interviews in the past but each experience should be different; because no -one wants to listen to you give a carbon copy speech on 10 different shows. Please read the notes.
