How would you answer difficult interview questions?

You can't be rude. You got that right. Public image can make or break a person. I have been in advertising and PR for over 40 years and have had to be nice. That seems hard for you. You can write down FAQ and have pat answers. You can say, give me a call at the office and I'll find some time to answer some of those questions. Don't give them a business card and make it easy for them to reach you. Let them do the research. Most people actually never follow up. If someone does call you can say it's not a good time and at least delay the process. If they persevere and call again accept the question and tell them you have to think about that more seriously because what worked for you is not necessarily right for them. Call them back during the day and probably you will get their machine message. You can either leave a quick answer or continue telephone tag. Come up with some answer because it is the persistent people that can bad mouth you because they expect an answer after all their hard trying. You can also hire someone in public relations as your agent and tell them call my assistant and they can help you. I have to run to another appointment and now I'm running late.
