  1. NCR's self-checkout systems process millions of transactions daily across global retailers. Describe how you would design a highly available, fault-tolerant payment processing microservice for this system, considering network latency in various regions and PCI DSS compliance.

    Software EngineerSystem Design, High Availability, Payments, SecurityTests: Evaluates understanding of distributed systems, security, and payment industry standards at NCR's scale.

  2. Imagine a bug report: 'After a network hiccup, an NCR Aloha POS terminal shows incorrect inventory counts for specific menu items, but only when processing an order modification mid-transaction.' Outline your debugging strategy, including potential tools and logs you'd investigate within an NCR hospitality environment.

    Software EngineerDebugging, Distributed Systems, POSTests: Assesses problem-solving skills, knowledge of troubleshooting complex, real-time systems like NCR Aloha.

  3. You need to optimize the response time for fetching customer loyalty points from a central database for NCR's retail loyalty program, which serves thousands of stores globally. How would you approach data caching and synchronization to ensure consistency and speed for both online and in-store transactions?

    Software EngineerPerformance Optimization, Caching, Data ConsistencyTests: Checks understanding of large-scale data management and performance for NCR's loyalty platforms.

  4. Write a function that, given a stream of NCR ATM transaction logs (each log containing `transaction_id`, `timestamp`, `atm_id`, `amount`, `status`), identifies all `transaction_id`s that were pending for more than 5 minutes before eventually succeeding. Assume the log stream is continuous and unordered.

    Software EngineerCoding, Stream Processing, Data AnalysisTests: Evaluates algorithmic thinking and handling real-time data from NCR's core banking products.

  5. NCR is migrating its legacy on-premise banking software to a new cloud-native platform. Discuss the architectural considerations and challenges you'd anticipate when moving a core banking application with strict uptime and security requirements to AWS or Azure.

    Software EngineerCloud Migration, Enterprise Architecture, SecurityTests: Probes experience with enterprise cloud transformation and critical system migration challenges at NCR.

  6. A new feature in NCR Voyix's retail platform requires showing real-time promotional offers based on a customer's current basket items and purchase history. How would you design an event-driven architecture to support this, minimizing latency and ensuring scalability across many stores?

    Software EngineerSystem Design, Event-Driven Architecture, Real-time ProcessiTests: Assesses ability to design scalable, real-time solutions for NCR's commerce platforms.
