Explanation
Hint: Identify the requirement first, then choose the approach that addresses the main constraints, trade-offs, failure modes, security, cost, and verification.
Correct answer: I would approach “How would you design least-privilege access for multiple application roles?” by clarifying the requirements first, then using these considerations: in a real interview, i would not jump straight to a technology choice. for “how would you design least-privilege access for multiple application roles?”, i would first identify actors and trust boundaries. then i would grant only the actions and resources each role needs and separate identities and workloads where appropriate. i would also protect secrets and sensitive data. finally, i would test policies and retain audit evidence. i would make the assumptions explicit and explain what evidence or production signals would make me revisit the decision.. I would state my assumptions and defend the trade-offs rather than presenting the choice as universally correct.
Why the alternatives are weaker:
- Using broad administrator permissions for convenience
- Not distinguishing authentication from authorization
- Skipping policy testing and auditability
What the interviewer is testing
- Trust boundaries
- Authorization design
- Auditability
Common Mistakes
- Using broad administrator permissions for convenience
- Not distinguishing authentication from authorization
- Skipping policy testing and auditability
Interviewer Follow-ups
- What assumptions would you clarify before committing to the design?
- What changes if the scale, reliability target, security requirement, or budget changes?
- What is the biggest failure mode in your proposed approach?
