What metrics would you focus on as the PM for YouTube?

When answering this question, concentrate on key performance indicators that align with YouTube's business goals, such as user engagement, retention, and monetization. Discuss metrics like watch time, daily active users (DAU), and subscriber growth, emphasizing how they reflect user satisfaction and platform health. Consider the balance between creator metrics (like upload frequency and engagement rates) and viewer metrics (like session duration and click-through rates). Be prepared to explain why each metric is important and how it can inform product decisions, as well as any potential trade-offs between metrics.
