Assume you are working on a consumer mobile app. Propose one product improvement that could improve user engagement, retention, or conversion. Your answer should cover: - What user problem you are solving. - Which user segment is affected. - The feature or product change you would build. - How you would implement it at a high level. - What success metrics you would use. - How you would design an A/B test or experiment to verify impact. - What guardrail metrics you would monitor. - Whether the change could negatively affect other users or parts of the product.
