  1. Imagine Airwallex is experiencing increased latency for cross-border payment processing to a specific Asian country. Outline your approach to debugging this issue, considering potential bottlenecks in our FX conversion services, nostro account reconciliation, or API gateways. What tools would you use, and what data would you collect first?

    Software EngineerDebugging and PerformanceTests: Assesses debugging skills, systematic problem-solving under pressure, and familiarity with distributed systems relevant to financial services.

  2. Design a distributed system for real-time fraud detection for large-volume international money transfers. Consider the trade-offs between latency, accuracy, and scalability. How would you handle eventual consistency for fraud alerts versus immediate transaction blocking?

    Software EngineerSystem DesignTests: Evaluates system design capabilities, understanding of distributed systems principles, and ability to balance competing requirements in a high-stakes environment.

  3. Write a SQL query to identify the top 5 most profitable currency pairs processed by Airwallex in the last quarter, considering both transaction fees and FX spreads. Assume tables for transactions, currency exchange rates, and fees.

    Software EngineerCoding and SQLTests: Tests SQL proficiency and understanding of financial data structures and profitability metrics.

  4. You've deployed a new algorithm to detect suspicious transaction patterns. After deployment, you observe a slight increase in false positives. How would you investigate this? What metrics would you track to confirm if the new algorithm is indeed worse, and what steps would you take to iterate on it?

    Software EngineerCoding and ReasoningTests: Measures analytical thinking, ability to debug and improve code, and data-driven decision-making for algorithmic changes.

  5. Given Airwallex's global infrastructure, design a scalable microservice for processing customer KYC (Know Your Customer) verification. How would you ensure data privacy and compliance with different regional regulations while handling high throughput?

    Software EngineerSystem DesignTests: Assesses architectural design skills for complex, regulated systems, focusing on scalability, security, and compliance.

  6. We want to build a feature allowing small businesses to automatically reconcile payments received through Airwallex with their internal accounting software. Describe the high-level architecture, key APIs needed, and potential data synchronization challenges.

    Software EngineerSystem DesignTests: Evaluates ability to design practical product features, understand integration complexities, and think about user workflows.
