What might help while interviewing some one is not to ask embarrassing questions. Also, asking questions that will make people sad will not help. You might also want to ask question that will interest people who are going to hear the interview. Boring questions might just get a smaller audience. Asking mean question that will make people feel insulted might not help either. More than one answer to a question might be interesting as well. One kind of a boring question is yes or no questions.
Some questions that are interesting are:
1.What is your sport and why?
2.What is your view on debates?
3.What do your plan for when your grown up?
