I have been asked before, and got an email earlier asking me again if I will do it.
When offered the interview, everyone who gets that mail has the opportunity to decline it.
I have taken that option.
I am not prepared to lie on it. And I am not prepared for a lot of people to know the truth.
Such information should remain private ;)
(I also think it would be terribly egotistical for me to do it seeing as I run that side of the UPB site).
