Difficulty Level

This is a senior-level C++ interview. Do not accept textbook definitions alone. Push for production examples involving memory ownership, concurrency bugs, performance tuning, and debugging difficult crashes. Ask follow-ups like 'Why did you choose that container?' 'What went wrong in production?' and 'How did you verify the fix?' Strong answers should show deep understanding of trade-offs, not just syntax familiarity.
