I don't have an iPod. I don't get the whole iPod thing. Who has time to listen to that much music? If I had one, it would probably have Sinatra, Beatles, some '70s music, some '80s music, and that's it.
My basic approach to interviewing is to ask the basic questions that might even sound naive, or not intellectual. Sometimes when you ask the simple questions like 'Who are you?' or 'What do you do?' you learn the most.
