Practice questions in GE Digital's style

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

  1. GE Digital's Predix platform processes vast amounts of time-series sensor data from industrial assets. Design a data structure and algorithm for efficiently storing and querying petabytes of this high-frequency sensor data, ensuring low latency for real-time anomaly detection and historical trend analysis.

    Software EngineerSystem Design / Data StructuresTests: Evaluates understanding of scalable data storage, time-series databases, and performance optimization for industrial data.

  2. You are developing a critical microservice within GE Digital's Asset Performance Management (APM) suite responsible for calculating real-time asset health scores. This service receives 10,000 updates per second per asset for hundreds of thousands of assets. Outline a robust error handling and retry strategy for external API calls made by this microservice to other Predix services, considering potential network partitions and ensuring data consistency.

    Software EngineerDistributed Systems / Error HandlingTests: Assesses knowledge of fault tolerance, retry mechanisms, and consistency in high-throughput distributed systems.

  3. A customer using GE Digital's Grid Solutions software reports that their energy distribution optimization algorithm is occasionally recommending suboptimal power flows, leading to temporary grid instability in specific regions. Describe your debugging process, starting from how you'd confirm the issue, isolate its root cause (software, data, or model), and propose a solution.

    Software EngineerDebugging / Problem SolvingTests: Examines structured debugging methodology, ability to handle complex system interactions, and critical thinking.

  4. GE Digital's edge devices often operate in harsh, remote industrial environments with intermittent network connectivity. Design a software update mechanism for these devices that ensures atomicity (all or nothing), provides rollback capability in case of failure, and minimizes operational disruption to critical industrial processes.

    Software EngineerSystem Design / Edge ComputingTests: Tests knowledge of robust update mechanisms for constrained and distributed edge environments.

  5. Write a Python function that consumes a stream of timestamped sensor readings (e.g., `[('2023-10-26T10:00:01Z', 150.5), ('2023-10-26T10:00:02Z', 151.2), ...]`) from a GE Gas Turbine. The function should detect and report the first instance where the 5-minute rolling average temperature exceeds a predefined threshold `T` by more than 10 degrees Celsius, within a window of the last 60 minutes. Optimize for memory and CPU usage on an embedded system.

    Software EngineerCoding / AlgorithmsTests: Evaluates algorithm design, time-series processing, and optimization for resource-constrained environments.

  6. Given GE Digital's focus on critical infrastructure, what specific security considerations would you prioritize when developing an API for a Predix-based application that allows remote configuration changes to industrial control systems, and how would you implement them?

    Software EngineerSecurity / API DesignTests: Assesses understanding of cybersecurity principles, secure API design, and their application in OT environments.
