Design a creator posting-frequency experiment
Company: TikTok
Role: Data Scientist
Category: Analytics & Experimentation
Difficulty: medium
Interview Round: Onsite
Overview: Design an experiment to test whether a push or email nudge raises how often creators post on a short-video platform, covering metrics, randomization, eligibility, and sample size. The hard parts are spillover between creators through shared viewers, creators who never open the nudge, and sample-ratio-mismatch checks.
