Your question is A/B Testing Experience. 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 a past experience of you conducting A/B testing.
Explain the experiment from initial hypothesis through final decision. Cover the primary metric, guardrails, minimum detectable effect, sample-size or power reasoning, unit of randomization, analysis plan, and any issues such as peeking, novelty, sample-ratio mismatch, or interference. Use real details where possible, but do not disclose confidential information.
