  1. Imagine Navan's travel booking platform is experiencing intermittent latency issues when users search for flights during peak hours. Outline your approach to diagnosing the root cause, considering the distributed nature of microservices and third-party API integrations. What metrics would you monitor?

    Software EngineerDebugging and PerformanceTests: Evaluates debugging skills in a complex, distributed system and understanding of performance metrics under load.

  2. Navan offers a unified platform for travel, corporate cards, and expense management. Design a system that allows a business to seamlessly reconcile an expense report filed by an employee against a flight booking made through Navan, including handling potential discrepancies (e.g., price changes, added baggage fees). Consider data consistency and API interactions between the travel and expense modules.

    Software EngineerSystem DesignTests: Assesses system design capabilities, ability to integrate disparate services, and understanding of data consistency challenges.

  3. You've identified a potential SQL injection vulnerability in the API endpoint that handles flight search queries. How would you mitigate this risk, and what steps would you take to ensure similar vulnerabilities are prevented in the future across the codebase?

    Software EngineerSecurity and CodingTests: Tests security awareness and practical coding practices for vulnerability prevention.

  4. Navan's engineers are building a new feature to automatically suggest optimal hotel bookings based on past travel patterns and calendar events. Describe the architectural considerations for this feature, focusing on data pipelines, machine learning model deployment, and real-time recommendation serving.

    Software EngineerSystem Design and ML IntegrationTests: Evaluates system design for ML-powered features and understanding of deployment pipelines.

  5. A critical microservice responsible for processing corporate card transactions is failing intermittently. Describe your strategy for identifying the bottleneck, whether it's CPU, memory, network I/O, or database contention. What tools would you use?

    Software EngineerDebugging and ObservabilityTests: Assesses practical debugging skills and familiarity with observability tools in a microservices environment.

  6. Navan has a significant user base of SMBs and larger enterprises. How would you design the authentication and authorization system to cater to both, considering features like SSO, role-based access control for different departments, and granular permissions for travel approvers?

    Software EngineerSystem DesignTests: Tests ability to design scalable and secure authentication systems for diverse user segments.
