Representative practice questions
These are practice questions written for this guide. They are not claimed to be questions this company has asked.
Given trip events (requested, accepted, started, completed, cancelled), write SQL that computes the cancellation rate per city per hour.
Design a pipeline that computes driver supply and rider demand per area every minute. How do you handle late GPS events?
How would you deduplicate trip events that a mobile client may send more than once?
A real-time metric and the next day's batch report disagree. How do you find out which one is wrong?
Tell me about a time you had to make a decision quickly with incomplete data.
Preparation overview
Prepare in three areas: technical fundamentals, data system design, and behavioural stories. Marketplace businesses depend on fresh, correct event data, so event-time processing and correctness are sensible themes to prepare; they are our suggestion, not a description of Uber’s interviews.
Technology focus
Revise event-time windows, watermarks and deduplication alongside SQL fundamentals: batch vs streaming, Kafka fundamentals, window functions.
System-design focus
Practise the real-time analytics pipeline and Kafka ingestion case studies.
Behavioural preparation
Prepare stories about acting with incomplete information, owning an incident, and working across teams.
