  1. Imagine Bolt is experiencing a surge in new driver sign ups in a specific city. A key API endpoint for driver onboarding is showing intermittent 5xx errors. How would you debug this issue, considering potential bottlenecks in our microservices, database, or third party integrations like identity verification?

    Software EngineerDebugging & System PerformanceTests: Evaluates debugging skills under pressure and understanding of distributed systems.

  2. Bolt's ride-hailing service operates in many cities with varying traffic patterns and user demand. Design a distributed system for real-time driver matching to passengers. Consider factors like latency, scalability to millions of concurrent requests, and fault tolerance.

    Software EngineerSystem DesignTests: Assesses ability to design scalable and resilient distributed systems for a high-traffic service.

  3. We are considering introducing a new feature allowing users to pre-book Bolt rides for specific times, similar to taxi services. Describe how you would implement the underlying scheduling and dispatch logic. What are the potential edge cases and how would you handle them?

    Software EngineerAlgorithm & Logic DesignTests: Tests logical thinking and the ability to design algorithms for complex operational scenarios.

  4. Bolt's platform handles millions of ride requests daily. We need to store and efficiently query historical ride data for analytics and compliance. Design a data model and a query strategy for this. What trade-offs would you consider regarding data consistency, query performance, and storage costs?

    Software EngineerData Modeling & DatabasesTests: Evaluates understanding of data storage, retrieval, and trade-offs in database design for large datasets.

  5. Write a Python function that, given a list of past Bolt rides with timestamps and locations, calculates the average estimated time of arrival (ETA) for a driver to reach a passenger in a specific zone, considering historical traffic data for that zone.

    Software EngineerCoding & Data ProcessingTests: Assesses coding proficiency and ability to process and analyze structured data.

  6. Imagine a scenario where Bolt Food delivery times are significantly increasing in a particular region due to driver availability issues. How would you identify the root cause using data, and what metrics would you track to confirm your hypothesis and measure the impact of any proposed solutions?

    Software EngineerData Analysis & Problem SolvingTests: Tests analytical skills and ability to use data to diagnose and solve operational problems.
