Suggested Approach

Start by acknowledging that success for TikTok is multi-dimensional, encompassing user growth, engagement, monetization, and ecosystem health. Then, as a software engineer, focus on how technical metrics like latency, scalability, and recommendation quality directly impact these business outcomes. Finally, tie your answer to TikTok's mission and long-term vision, showing you understand the company's unique position in the market.

Pro tip: Emphasize that success isn't just about vanity metrics like downloads; it's about sustained engagement and monetization. Show you understand the balance between user experience and business goals, and how engineering decisions influence both.
