How these map to the Meta loop

These are Analytical Reasoning cases: an ambiguous prompt you structure, a metric you define, and a recommendation you defend while the interviewer adds constraints. On WhatsApp the constraint they love to add is privacy — you can't read message content — so every answer has to build its measurement from metadata and opt-in signals, and protect the private core.

Each answer is a coaching walkthrough: a Sample answer (clarify → approach → a simulated back-and-forth → a clear call), then a Deep dive with illustrative example, then a Grading rubric.
