Has someone suggested whiteboard proficiency is sufficient by itself?

Fair point, that is a straw man. I haven't experienced an all-whiteboard interview - there's always been more to it.

The whiteboard is meant to filter out people who suck.

I think that's what some interviewers have missed. They jump straight in at the deep end with difficult algorithmic puzzles, and don't ever do an easy one. I have experienced this.

Yeah, I have hard algorithm questions I ask, but I don't open with them, and I know they are hard. I expect them to possibly fill the entire remaining time.

Also, for the hard question, it's not even about getting it "right": the one person I ever had get my hardest question right was flushed by other people in my process, and I've hired many people who never got close. I want to see how they try.
