What metrics would you track to evaluate a new ‘Top Picks’ ML feature for Netflix?

Focus on identifying both user engagement and content performance metrics that reflect the effectiveness of the 'Top Picks' feature. Consider metrics such as click-through rate (CTR) on recommendations, user retention rates, and the time spent watching content suggested by the feature. Additionally, think about how to measure user satisfaction, perhaps through surveys or NPS scores, and analyze the impact on overall viewing hours. Be prepared to discuss how these metrics can inform iterative improvements to the feature and align with Netflix’s broader business goals.
