I do not "trial and error" my way to correct answers, but I complain bitterly about whiteboard interviews. It's the wrong medium. I wouldn't mind at all being asked to use a pack of cards as a prop to talk through a sort algorithm, but asking me to write one out on a whiteboard is just hamstringing me.

That is a valid objection. It's best to use the right tool to communicate about the problem and solution.
