Your question is A/B Testing Design Questions. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about your approach to designing A/B tests and experimentation plans.
Cover the process from hypothesis formation through the ship decision. Explain how you choose the randomization unit, define a primary metric and guardrails, set an explicit MDE, estimate sample size under realistic traffic and time constraints, and pre-register the analysis. Discuss how you would handle peeking, multiple comparisons, sample ratio mismatch, novelty effects, network interference, SUTVA violations, and differences between the randomization and analysis units.
Use a practical structure and state the assumptions behind your recommendations.
