How would you answer an interview scenario involving SOLID tradeoffs?

For an interview scenario involving SOLID tradeoffs, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. SOLID principles are design heuristics for managing change, not mandatory rules that maximize abstraction in every class. In this scenario, a small internal CRUD service has extensive interfaces and factories. Explain how you would judge whether SOLID has been over-applied. For production, optimize for likely change, team understanding, testability, and operational needs; introduce abstractions where they pay for themselves. 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.
