@miah Indeed, it's very grounded in reality because the question's based on a ticking-clock problem I faced. Honestly, in my career, if someone could actually root cause some mystery issue and scribble out their solution on a cocktail napkin, I could code it for them at that point. I don't think I've ever had a situation where being 20% more awesome at a given language actually helped anything. Someone who can prove the IR sensor is failing because of temperature? Golden.
