I am doing just that.

Not always. I've done a lot of whiteboard interviews too. It's a different way to discuss a problem, and one that people do use at work.
Most design sessions happen with a colleague or two in front of a whiteboard, not sitting at a workstation.
I disagree that blacking out is so common, though I understand it does happen occasionally. Also, we typically do at least 5 interviews in every onsite, one blackout wouldn't destroy the chances of an otherwise strong candidate.
