Evaluate Push Notification Impact on Rideshare Supply Shortages
Company: Uber
Role: Data Scientist
Category: Analytics & Experimentation
Difficulty: hard
Interview Round: Technical Screen
##### Scenario
Rideshare airport surge pricing push notifications need rigorous measurement of causal impact
##### Question
Design an experiment to evaluate the effectiveness of the push notification on resolving supply shortages. Specify success metrics, driver-level A/B setup, how to handle spill-over effects, and how you will establish causality.
##### Hints
Think cluster randomization, geo-split, CUPED, difference-in-difference, guard-rail metrics, and contamination checks.
Quick Answer: This question evaluates a data scientist's ability to design and analyze experiments for causal impact measurement, assessing competency in metric selection, appropriate randomization units, spillover and contamination management, and statistical inference.
