  1. FourKites tracks millions of shipments daily. Describe how you would design a system to ingest, process, and make searchable real-time location updates from various carrier APIs (e.g., truck GPS, ELD devices, ocean vessel AIS) at this scale, considering potential data volume spikes and API rate limits.

    Software EngineerSystem DesignTests: Evaluates the candidate's ability to design scalable, fault-tolerant distributed systems for high-throughput data ingestion and processing.

  2. Imagine a scenario where a critical customer reports that their real-time shipment visibility is intermittently failing, showing outdated locations for a specific carrier. How would you approach debugging this issue in a distributed microservices environment?

    Software EngineerDebuggingTests: Assesses problem-solving skills, logical deduction, and understanding of distributed system debugging techniques.

  3. FourKites' platform relies on accurate ETA (Estimated Time of Arrival) predictions. How would you design a machine learning model to predict ETAs for different modes of transport (e.g., truckload, LTL, ocean), incorporating real-time traffic, weather, driver behavior, and historical route performance?

    Software EngineerMachine LearningTests: Tests the candidate's understanding of ML system design, feature engineering, model selection, and deployment in a production environment.

  4. Consider the challenge of identifying and deduplicating duplicate shipment events coming from multiple sources (e.g., a carrier API and a direct EDI feed). Outline an algorithm or approach to handle this at scale, minimizing false positives and negatives.

    Software EngineerAlgorithmsTests: Examines the candidate's ability to design efficient algorithms for data quality and integrity challenges.

  5. FourKites uses a graph database to represent complex supply chain relationships. How would you query this graph to find all shipments that are delayed and directly impact a specific critical inbound shipment for a major automotive customer?

    Software EngineerDatabasesTests: Evaluates understanding of graph database concepts and ability to translate business problems into graph queries.

  6. You are tasked with building a new feature that allows users to define custom alerts based on various shipment events (e.g., delay, dwell time exceeding X hours, arrival at a specific geofence). Describe the backend architecture considerations for implementing a robust and scalable alerting system.

    Software EngineerSystem DesignTests: Assesses architectural design skills for event-driven systems and real-time notification mechanisms.
