Suggested Approach

Structure your answer as a concise narrative that connects your past roles, key projects, and measurable impact, tailored to TikTok's data science needs. Focus on 2-3 projects that demonstrate product analytics skills and adaptability in ambiguous situations, quantifying outcomes where possible.
