How would you answer an interview scenario involving Document chunking?

For an interview scenario involving Document chunking, I would first clarify the business goal, scale, constraints, and the failure or quality attribute the interviewer wants to explore. Chunking splits source documents into retrieval units that can be embedded, indexed, and supplied to a model. 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.
