My company makes us interview with whiteboard problems. It's stupid but not my decision. My favorite spin on this is the reverse problem. Ask the candidate to talk about, solve, and explain their favorite whiteboard-style problem. Ask them for something they were initially intimidated by. Maybe ask them a slight twist of it. We all know candidates study riddle problems, so let's both take advantage of that rather than giving an anxiety-test even if it's phrased as low-key.
