Generally I try to head this off before I even get into the situation. I will boldly ask whether there will be any white boarding during an interview. If there is I will often explain why that's not a good idea and see what else they would be willing to do to interview me. The discussion is usually very valuable to both of us. I also will bring a laptop with me to the interview. If it turned out they would like to ask me a white boarding question while I am there I have said "I would much prefer we pair on a solution to that together. I have my laptop here. Why don't we get started? I bet we could deploy something in the next 10 minutes." This often leads to, again, either a good discussion or even better an actual pairing session which teaches me about my interviewer and them about me. If they really insist I whiteboard something, I will say no unless it's a problem that really interests me.
