Welcome to your interview.
The question is on your right: Missing a Critical Performance Target. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Tell me about a time you failed to meet an important target. What was the target, why did you miss it, how did you communicate it, and what did you change afterward to recover or pivot?
