Structure a Perfect STAR Answer for a Behavioural Question

Act as an interview preparation coach. I need to answer this behavioural interview question: [INTERVIEW_QUESTION]. Here is a rough description of a relevant experience I can use: [ROUGH_EXPERIENCE]. Structure this into a polished STAR answer (Situation, Task, Action, Result). The Situation should be 2 sentences, Task 1 sentence, Action should be 3–4 specific steps I took, and Result must include a quantified outcome or clear impact. Total spoken length: approximately 2 minutes. Also flag what the interviewer is really testing with this question.
