Anchor every STAR element on evidence, quantified impact, and prevention : that is what separates a senior answer from a junior retelling.
Missing a deadline is a fact; how early you communicate it and what you fix afterward is what defines you.
Stabilize first, then find the root cause methodically, fix, verify, and add prevention : show calm and a repeatable method.
In production, contain first, fix second, communicate throughout, and prevent recurrence last : and own every step.
