> why do you still ask a question you've gotten zero signal from? Interview questions aren’t just for comparing candidates with each other. It’s also useful to know how a candidate’s knowledge compares to the knowledge of the team. The best of a bad bunch might still be unhirable. It’s often better to leave a role vacant than fill it with someone mediocre. If the GP can’t find anyone in the hiring pool who knows C++ well, that’s a valuable insight. Maybe they need to expect less C++ from candidates and plan for more on the job training. Or change languages.
