What a strong answer covers

Try it out loud first. Then check yourself:

  1. Map the data: what is collected, how sensitive it is, where it flows and is stored, and who can reach it.
  2. Check identity and access end to end: user auth, service-to-service auth, admin paths, and how secrets are issued and rotated.
  3. Look at failure and abuse: trust boundaries, third parties, logging for investigations, and blast radius if one part is compromised.
  4. Return risk-rated findings with a recommended fix and an owner, separating launch blockers from follow-ups.

If the interviewer pushes back
