That's a shame. When someone sails through something I gave them, I usually kick myself for giving them a crappy or cliched problem and assume they've probably solved it previously. In that situation I absolutely am trying to figure out if they at least understand the answer so I'm looking for them to talk through, etc.

Coding on the board is a broken process anyway (just one I rarely have the influence to redefine wholly) but coding on the board as a "closed" interview question is downright stupid. You learn absolutely nothing relevant about the candidate, and they learn absolutely nothing about you. I'm sorry to find out that was the bulk of your experience.

FWIW, once you get enough experience to pick and choose, that would be a bad smell for me interviewing at a company. If I feel like there's no rapport and I'm just getting grilled in an interview past the initial tech screen, I will and have stopped the process myself. Life's too short to be a cog.
