I acctually love questions about how to best traverse a tree, binary or not. Maybe I'm ready for an interview at least? But why is it me who should be put through a four-hour white board coding session? I would collapse after 40 minutes. They can code. Why can't they be the ones at the white board? I can "architect" and correct their mistakes. They would still be able to evaluate my competence.
