Doing a great interview is an acquired skill and art. Unfortunately there really aren’t any great books on the topic either. Maybe it’s time to write one. There’s a lot more to it than just asked no a bunch of questions. Canned interviews sound canned and will not generate interest. You’ve got to find the angle. You need to find a side of your subject that isn’t well known or common knowledge. Are with a different perspective you can make a difference. Just put your mind to it and think differently. When it comes to interviewing it’s all about practice and point of view. You need to stand out. And remember that the most difficult subjects provide you with an incredible challenge to grow and improve your skills
