Your question is Optimize Code Beyond Timing Budget. 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).
Describe a time you had to optimize a piece of code that was exceeding its timing budget.
Explain how you measured the overrun, identified the bottleneck, selected an optimization, and verified that the change met the timing requirement without introducing functional, concurrency, memory-safety, or security regressions. Be prepared to discuss trade-offs, failed approaches, and how you would respond if optimization could not recover the full budget.
