  1. Imagine Virtusa is building a new platform to help enterprises manage their cloud migration. Design the high-level architecture for a service that analyzes an enterprise's existing IT infrastructure and recommends optimal cloud solutions, considering aspects like cost, performance, and security. How would you handle scalability for millions of infrastructure assets?

    Software EngineerSystem DesignTests: Evaluates ability to design scalable and robust distributed systems, considering common enterprise challenges in cloud adoption.

  2. A critical Virtusa digital transformation project is experiencing intermittent latency issues affecting its core banking module. Users report slow transaction processing. How would you approach debugging this problem, starting from the user report to identifying the root cause across potential layers (application, network, database)?

    Software EngineerDebuggingTests: Assesses systematic troubleshooting skills and understanding of distributed system components.

  3. Virtusa provides AI-powered solutions for customer service automation. If a client reports that the AI chatbot is misinterpreting user intents for complex queries related to insurance claims, how would you identify the specific failure points in the model pipeline (NLU, dialogue management, backend integration) and propose a solution?

    Software EngineerDebuggingTests: Tests problem-solving in AI/ML application contexts and understanding of common failure modes.

  4. You are tasked with optimizing the performance of a microservice responsible for generating reports for Virtusa's clients. The service currently takes 30 seconds to generate a complex report. What specific techniques (e.g., caching, database optimization, asynchronous processing) would you explore to reduce this latency, and how would you measure their impact?

    Software EngineerPerformance OptimizationTests: Evaluates knowledge of performance tuning strategies in a microservices environment.

  5. Given Virtusa's focus on digital transformation and data analytics, consider a scenario where we are developing a recommendation engine for an e-commerce client. Design the core components and data flow for a system that suggests personalized product recommendations based on user behavior and purchase history. How would you handle cold-start problems for new users or products?

    Software EngineerSystem DesignTests: Assesses understanding of recommendation system architecture and common challenges.

  6. Write a SQL query to find the top 3 enterprise clients of Virtusa (based on contract value) who have engaged with our digital transformation services for more than 5 projects in the last two years. Assume you have tables `Clients` (client_id, client_name, contract_value) and `Projects` (project_id, client_id, service_type, start_date).

    Data ScientistSQLTests: Tests SQL proficiency for data retrieval and basic aggregation.
