- You named the problem
- End-to-end ownership - you didn't wait to be told what to secure
- You scoped by blast radius
- Threat-modeling judgment and the discipline to not gold-plate
- You shipped behind a flag
- Pace with a reversible bet, not heads-down perfectionism
- You worked cross-functionally
- Systemic threat-surface reduction, not a siloed one-off fix
- You measured the result
- A defensible outcome the interviewer can grade you on
“No one owned what our coding agent was allowed to execute and that kept me up at night - an indirect prompt injection could turn a file read into rm -rf on a user's repo. I scoped it to command execution first, since that's the worst outcome and shipped a deny-by-default executor behind a flag: agents could run a small allowlist, anything else queued for a human. We watched the deny logs for a week, widened the allowlist from real usage and within a month every agent command on customer machines went through that chokepoint. I defined the problem, picked the riskiest slice and shipped something reversible instead of waiting for a perfect policy.”
When they ask how you handled the ambiguity, narrate the threat model you ran in your head to scope it. “I ranked the surfaces by blast radiusHow much breaks if a change goes wrong; the scope of potential damage.

A story that's all planning and no shipping fails this round. On a flat, fast team, “I wrote a comprehensive proposal and socialized it for a quarter” reads as someone waiting for permission. Make sure your story has a thing that shipped and a number, even if the first version was small and stubbed at the edges.
