How would you answer an interview scenario involving Repository pattern?

For an interview scenario involving Repository pattern, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Repository provides a domain-oriented abstraction over data access and persistence operations. For production, expose intent-based methods, keep query ownership clear, avoid leaking persistence details, and use the pattern only when it adds a useful boundary. I would then explain the main alternatives and tradeoffs, identify likely failure modes, and describe how I would validate the solution through testing, observability, security controls, and recovery or rollback planning.
