  1. Imagine Flexport's global freight forwarding platform is experiencing increased latency during peak shipping seasons, specifically affecting the real-time tracking module. How would you diagnose the root cause, considering potential bottlenecks in our microservices architecture, database performance, or external API integrations with carriers?

    Software EngineerDebugging & System PerformanceTests: Evaluates problem-solving skills, understanding of distributed systems, and ability to diagnose complex performance issues in a production environment.

  2. Design a system to ingest and process real-time shipment status updates from hundreds of different carrier APIs, each with its own format and reliability. The system must be scalable to handle millions of updates per day and ensure data consistency across Flexport's platform.

    Software EngineerSystem DesignTests: Assesses system design capabilities, understanding of data pipelines, fault tolerance, and scalability for high-volume data ingestion.

  3. A customer reports that their shipment is showing as 'delivered' in Flexport's system, but they haven't received it. Walk me through the steps you would take to investigate this discrepancy, what data you would look for, and how you would communicate with the customer and relevant internal teams (e.g., operations, carrier relations).

    Software EngineerDebugging & Customer ImpactTests: Tests debugging skills in a customer-facing scenario, cross-functional communication, and understanding of operational workflows.

  4. We are considering using a new third-party logistics provider (3PL) to expand our network in Southeast Asia. How would you design a solution to integrate their booking and tracking APIs into Flexport's existing platform, ensuring data mapping, error handling, and minimal disruption to our current operations?

    Software EngineerSystem Design & IntegrationTests: Evaluates ability to design scalable integrations with external systems, manage data complexities, and consider operational impacts.

  5. Write a SQL query to find the top 10 most frequently booked trade lanes (origin-destination pairs) for FCL (Full Container Load) shipments in the last quarter, excluding shipments that were cancelled.

    Data ScientistSQL & Business MetricsTests: Assesses SQL proficiency and ability to extract key business insights from data.

  6. Flexport wants to understand the impact of offering a new customs brokerage service on existing ocean freight bookings. How would you design an A/B test or an observational study to measure this impact, what metrics would you track, and what are potential confounding factors?

    Data ScientistExperiment Design & Causal InferenceTests: Tests understanding of experimental design, causal inference, and ability to measure the impact of new product features.
