I had a decent example ready but I fumbled the structure a bit.
Choose a specific experiment where you can clearly articulate the hypothesis, metrics, and outcome. Structure your answer using a framework like STAR, but emphasize the experimental design, data analysis, and decision-making process. Highlight how you collaborated with cross-functional teams and what you learned.
Pro tip: Quantify the impact of the experiment and discuss trade-offs, such as statistical significance vs. practical significance, to show depth. Also, mention how you ensured the experiment was ethical and unbiased.
Briefly describe the product, the problem you were solving, and why it was important. Mention the target user segment and business goal.
Clearly articulate the hypothesis you were testing, including the expected outcome and the rationale based on data or user research.
Explain the experimental design: control and treatment groups, sample size, duration, and success metrics (primary and guardrail). Mention any tools used (e.g., A/B testing platform).
Describe the results, including statistical significance and effect size. Discuss any unexpected findings or segments that behaved differently.
Explain the decision made based on the results (ship, iterate, or kill) and the impact on the product. Mention next steps or follow-up experiments.
