Practice questions in Uber's style

Original ZorixOS questions written the way Uber interviews, so you rehearse the real format. Not claimed as asked at Uber.

  1. You are given a dataset of completed Uber trips in a city. Design a SQL query to identify the top 5% of drivers based on their average earnings per hour, considering only drivers who completed at least 50 trips. The dataset includes trip_id, driver_id, start_time, end_time, and fare_amount.

    Data ScientistSQL, MetricsTests: Evaluates ability to write complex SQL queries to extract meaningful business insights and handle data aggregation and filtering.

  2. Uber is considering a new feature to allow riders to book a trip for someone else (e.g., a parent booking for a child). What are the key metrics you would track to measure the success of this feature, and why?

    Product ManagerMetrics, Product StrategyTests: Assesses understanding of product success metrics and ability to connect them to business objectives.

  3. Imagine you are an Uber driver. You notice a significant increase in surge pricing in your area, but passenger demand doesn't seem to have increased proportionally. How would you investigate this discrepancy, and what actions might you consider?

    Data ScientistMetrics, Marketplace DynamicsTests: Tests ability to identify and diagnose potential issues in a complex marketplace and reason about causal relationships.

  4. Design a system to handle real-time matching of riders to drivers on Uber. Consider scalability, latency, and fault tolerance. What are the key components and their interactions?

    Software EngineerSystem Design, ScalabilityTests: Evaluates system design skills, focusing on distributed systems, real-time processing, and handling high concurrency.

  5. Describe a time you had to influence a team or stakeholder to adopt a technical solution you believed in, even when there was resistance. What was the situation, your approach, and the outcome?

    BehavioralInfluence, Stakeholder ManagementTests: Assesses ability to persuade and lead others through technical recommendations.

  6. Uber Eats wants to improve the conversion rate from restaurant browsing to order placement. Propose a product strategy, including key features and how you would prioritize them. What are the potential risks?

    Product ManagerProduct Strategy, Feature DevelopmentTests: Measures product strategy formulation, feature ideation, prioritization skills, and risk assessment.
