  1. Imagine our trading system experiences a microsecond delay in processing a market data tick. How would you approach debugging this in a high-frequency trading environment, considering the cascading effects on order execution?

    Software EngineerDebugging and PerformanceTests: Assesses debugging skills in a critical, low-latency system and understanding of distributed system impacts.

  2. Design a system to detect and mitigate 'quote stuffing' attacks on our exchange, where malicious actors flood the market with excessive orders to disrupt pricing. Consider latency, throughput, and fairness.

    Software EngineerSystem DesignTests: Evaluates system design capabilities for security and high-throughput trading environments.

  3. You're building a new feature for our Options trading platform that requires low-latency data aggregation across multiple sources. Outline the architectural choices and trade-offs you'd consider for the data ingestion pipeline.

    Software EngineerSystem DesignTests: Tests understanding of distributed systems architecture and data pipelines in a trading context.

  4. Write a Python function that takes a list of trades (symbol, price, volume, timestamp) and returns the average volume-weighted price for a given symbol within a specified time range. Discuss its time complexity.

    Software EngineerCoding and AlgorithmsTests: Measures basic coding proficiency and understanding of algorithm efficiency.

  5. Our order matching engine needs to be optimized for speed. Describe how you would profile and identify bottlenecks in a C++ codebase responsible for matching buy and sell orders.

    Software EngineerPerformance OptimizationTests: Evaluates practical knowledge of performance profiling and optimization techniques in a C++ trading system.

  6. How would you design a distributed caching system for real-time market data to minimize read latency while ensuring data consistency across multiple nodes?

    Software EngineerSystem DesignTests: Assesses design skills for distributed systems, focusing on low-latency data access and consistency.
