  1. Imagine Jump Trading is developing a new low-latency order routing system. Describe the key components you'd consider and the trade-offs between different approaches for ensuring message delivery with minimal delay, especially during periods of high market volatility. How would you handle potential network congestion between exchanges?

    Software EngineerSystem DesignTests: Evaluates ability to design scalable, low-latency systems and reason about distributed systems challenges.

  2. You've identified a bug in our high-frequency trading matching engine that is causing occasional, intermittent order discrepancies. Walk me through your process for diagnosing and fixing this bug. What tools and techniques would you employ, and how would you verify the fix without impacting live trading?

    Software EngineerDebuggingTests: Assesses debugging skills in a high-stakes, low-latency environment and problem-solving under pressure.

  3. Consider Jump Trading's market data feed handler. How would you design a system that can ingest, process, and distribute real-time market data from multiple global exchanges with sub-millisecond latency? Discuss data serialization formats, network protocols, and fault tolerance mechanisms.

    Software EngineerSystem DesignTests: Tests understanding of real-time data processing, low-latency systems, and distributed architectures at scale.

  4. Write a Python function to implement a Least Recently Used (LRU) cache suitable for caching frequently accessed instrument symbols and their latest prices. Consider thread safety and memory constraints in a high-throughput environment.

    Software EngineerCodingTests: Evaluates core data structure implementation skills and considerations for concurrent environments.

  5. We are experiencing significant latency spikes in our options pricing model computations during peak trading hours. Propose a strategy to identify the root cause. This might involve profiling code, analyzing hardware utilization, or examining external dependencies. How would you approach optimizing this for speed?

    Software EngineerPerformance OptimizationTests: Measures analytical skills in identifying performance bottlenecks and proposing solutions.

  6. Describe how you would implement a distributed rate limiter for API requests to our proprietary trading platforms to prevent abuse and ensure fair usage. What data structures and algorithms would be appropriate, and how would you handle synchronization across multiple servers?

    Software EngineerSystem DesignTests: Probes knowledge of distributed systems, concurrency control, and practical application of algorithms.
