Your question is Using STAR to Show Impact. 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).
Using the STAR method, provide one example when your actions made a change.
Keep your answer focused on a single situation, what you personally did, and the measurable difference that followed. The interviewer is looking for ownership, initiative, and evidence that your actions changed the outcome, not just that you were involved.
