Problem

Scenario

You work on a digital product and have used A/B testing to compare two experiences, such as a change to onboarding, navigation, or content presentation. The goal was to answer a concrete product or research question while balancing user impact and business outcomes.

Question

Have you ever used A/B testing in your research or product work? What was the question, how did you design and evaluate the experiment, and what did you learn from the results?

What this tests

  • Ability to frame a clear experimental question
  • Metric selection: primary, guardrails, and secondary metrics
  • Power analysis with an explicit MDE
  • Awareness of peeking and other experimentation pitfalls
