Problem

Explain an A/B test result you have interpreted before, including what you concluded and what you would do next.

Describe the hypothesis, unit of randomization, primary metric, guardrails, observed effect, uncertainty, and business decision. Include how you would validate the result, check for pitfalls such as peeking, sample ratio mismatch, novelty, or interference, and decide whether to ship, iterate, or run another test. Use a real example from your experience, but anonymize confidential details.
