Describe one project where you took a calculated risk that was outside your formal responsibilities. Context: What was the business or research goal, constraints, and the significant obstacles you anticipated? Action: What options did you evaluate, what data or experiments reduced uncertainty, and how did you dive deeper than your existing knowledge (specific sources, prototypes, or analyses)? Risk management: What was your pre-mortem, fallback, and guardrails? Result: Quantify the outcome with concrete metrics (e.g., dollars saved, lift, latency, accuracy) and timelines. Reflection: What would you change in hindsight, and how did you scale or generalize the approach for others?
