  1. Imagine Capgemini is developing a new AI powered platform for financial services clients to automate compliance checks. Describe the high-level system architecture, considering aspects like data ingestion, processing, AI model deployment, and client interaction. What are the key scalability challenges you foresee at global scale?

    Software EngineerSystem DesignTests: Evaluates system design thinking, scalability considerations, and architectural choices for large-scale enterprise solutions.

  2. You are tasked with debugging a performance issue in Capgemini's internal collaboration tool, which is experiencing slow response times for users across different time zones. Users report delays in chat messages and document uploads. How would you approach diagnosing and resolving this issue, given the distributed nature of the user base and potential network latency?

    Software EngineerDebuggingTests: Assesses problem-solving methodology, debugging skills in a distributed environment, and performance optimization strategies.

  3. Capgemini is building a cloud-native platform to help clients migrate their legacy applications. Describe the core components of such a platform, focusing on how you would handle data security, identity management, and automated testing for migrated applications.

    Software EngineerSystem DesignTests: Tests understanding of cloud architecture, security best practices, and automation in application modernization.

  4. Write a Python function to efficiently process a large stream of incoming client project data. Each record contains project ID, client name, start date, and estimated completion date. The function should identify projects that are at risk of exceeding their estimated completion date by more than 15 days, considering today's date. Assume data arrives in batches and needs to be processed with low latency.

    Software EngineerCodingTests: Measures coding proficiency, algorithmic thinking, and ability to handle data processing efficiently.

  5. A Capgemini client in the retail sector is experiencing issues with their e-commerce platform's recommendation engine, leading to low conversion rates. The engine uses collaborative filtering. Propose a debugging strategy for identifying potential causes, ranging from data quality to algorithm implementation.

    Software EngineerDebuggingTests: Evaluates analytical skills, debugging approach for complex systems, and understanding of recommendation engine fundamentals.

  6. Imagine Capgemini is building a real-time anomaly detection system for IoT devices deployed by its manufacturing clients. Describe the architecture of such a system, including data ingestion, feature extraction, anomaly scoring, and alerting mechanisms. How would you handle data volume spikes?

    Software EngineerSystem DesignTests: Assesses knowledge of real-time systems, IoT data processing, anomaly detection, and handling high-throughput data.
