Deliver an elevator pitch and impact example

In 60 seconds, deliver your elevator pitch: who you are, the scale you’ve operated at, and your superpower. Then walk through one experimentation project that drove a measurable business impact end‑to‑end: problem framing, hypothesis, unit of randomization, primary and guardrail metrics, sample size/power, duration, pre‑registration/analysis plan, execution challenges, and final results with concrete numbers (e.g., +X% conversion at Y% significance, Z p.p. change in a guardrail). Explain the causal story (why it worked), trade‑offs you considered, and what you would do differently. Finally, answer “Why Meta?”—map your motivations to a specific product surface you’d join and how your skills fit the role.
