  1. Imagine you are building a new real-time news feed for Reuters Professional, a product used by financial professionals. How would you design the system to handle millions of updates per second, ensure low latency, and maintain data integrity across distributed nodes? Consider potential failure modes and how to mitigate them.

    Software EngineerSystem DesignTests: Assesses ability to design scalable, fault-tolerant real-time systems and handle high throughput.

  2. We have a legacy system that generates irregular data dumps of legal case information. Users are complaining about missing or outdated entries in our Westlaw Edge platform. How would you approach debugging this issue? What tools or techniques would you use to identify the root cause of data discrepancies?

    Software EngineerDebuggingTests: Evaluates problem-solving skills, systematic debugging approach, and understanding of data pipelines.

  3. Describe a scenario where you had to optimize a computationally intensive algorithm used in a financial data processing service. What was the problem, what approach did you take, and what were the results in terms of performance improvements? Consider the trade-offs.

    Software EngineerCoding Reasoning/OptimizationTests: Tests understanding of algorithmic complexity, performance optimization techniques, and trade-off analysis.

  4. Thomson Reuters' Eikon platform aggregates vast amounts of financial market data. If we were to introduce a new feature that requires processing and displaying derivative contract data in real-time, what data structures and caching strategies would you consider to ensure efficient retrieval and display for thousands of concurrent users?

    Software EngineerSystem Design/Data StructuresTests: Assesses knowledge of appropriate data structures and caching mechanisms for high-performance financial data applications.

  5. Consider our ONESOURCE platform for tax compliance. If a user reports that the tax calculation for a specific cross-border transaction is incorrect, how would you go about verifying the calculation logic and identifying potential bugs in the underlying tax codes or data feeds?

    Software EngineerDebugging/ReasoningTests: Evaluates logical reasoning, understanding of complex business rules, and systematic debugging of calculation logic.

  6. We are developing a new AI-powered research assistant for legal professionals. Describe the architecture you would propose for the natural language processing (NLP) pipeline, focusing on how to handle potentially sensitive client data securely while achieving high accuracy in legal document analysis.

    Software EngineerSystem Design/AI/SecurityTests: Tests ability to design complex systems involving AI/ML with a focus on security and data privacy.
