Your question is Optimize Production Code. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain a time you had to optimize a piece of code that was performing poorly in production. Be specific about how you identified the bottleneck, evaluated trade-offs, worked with others, and validated the improvement. Focus on your individual contribution, the production impact, and what you learned.
