Your question is Root-Causing Recurring Model Failures. 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).
Give an example of a time you dived deep into a complex production failure to root-cause a recurring model error.
Explain how you separated symptoms from the underlying cause, prioritized competing hypotheses, and worked with relevant partners to restore reliable model behavior. Cover the actions you personally took, how you used production evidence, the resulting impact, and what you changed to prevent recurrence.
