• Research Tubi's content library, user base, and recent news to demonstrate genuine interest in their business. In your cover letter or interviews, connect your past experience to the specific challenges mentioned in the JD, like content performance measurement or viewer engagement.
• Quantify your impact in previous roles, especially any experience related to A/B testing, content/product analytics, or personalization. Highlight specific projects where you used SQL, Python, and Spark to analyze large datasets and drive business decisions. Emphasize your experience in translating technical findings into clear recommendations for non-technical stakeholders, such as product managers or executives.
• Brush up on advanced causal inference techniques beyond standard A/B testing, such as difference-in-differences or regression discontinuity. Practice explaining complex analytical concepts and results in simple, business-oriented language. Familiarize yourself with the streaming media and AVOD (Advertising-Based Video on Demand) business model and its key metrics.

面试指南

• Use the STAR method (Situation, Task, Action, Result) to structure your answers, focusing on your specific actions and the quantifiable impact of your work. For technical questions, explain your thought process step-by-step, demonstrating both your technical depth and your ability to communicate it clearly. For business influence questions, highlight how you collaborated with stakeholders, managed expectations, and ensured your insights were actionable.
• Walk me through a complex A/B test you designed and analyzed. What was the hypothesis, how did you ensure statistical validity, and what was the business outcome? Describe a time you had to analyze a large, messy dataset. What tools (SQL, Python, Spark) did you use, and what was the key insight you uncovered? How do you explain the results of a statistically significant but counterintuitive A/B test to a product manager who disagrees with the finding? Tell me about a project where your data analysis influenced a major business or product decision. What was your specific contribution? (For experienced candidates) How would you approach measuring the long-term impact of a new content recommendation algorithm versus its short-term engagement metrics?
• Prepare 2-3 detailed project case studies that showcase your skills in experimental design, data analysis with the mentioned tools, and business impact. Review fundamental and advanced concepts in statistics, probability, and experimental design. Be ready to write and explain snippets of SQL or Python/Pandas code for data manipulation and analysis during a technical screen.
