  1. Imagine a scenario where a core Guidewire BillingCenter module experiences a 20% increase in transaction processing time during peak hours. How would you approach diagnosing the root cause, considering potential bottlenecks in database performance, application code, or external integrations? Describe your debugging process.

    Software EngineerDebugging and PerformanceTests: Evaluates a candidate's systematic approach to identifying performance issues in a complex enterprise system.

  2. Guidewire PolicyCenter handles millions of policy transactions daily. Design a scalable and resilient system for ingesting and processing these policy updates from various external carrier systems. Consider aspects like data validation, error handling, idempotency, and eventual consistency.

    Software EngineerSystem DesignTests: Assesses system design skills, scalability considerations, and understanding of distributed systems in an insurance context.

  3. A customer reports intermittent failures when trying to retrieve policyholder data via the Guidewire Digital API. The logs show occasional connection timeouts to the underlying PolicyCenter database. What are potential reasons for this, and how would you investigate and mitigate this issue?

    Software EngineerDebugging and API PerformanceTests: Tests problem-solving skills in diagnosing intermittent issues and understanding API-database interactions.

  4. Guidewire Cloud Platform relies on microservices. How would you design a distributed tracing system for Guidewire's core services (e.g., PolicyCenter, BillingCenter, ClaimCenter) to monitor request flows and identify latency issues across services?

    Software EngineerSystem Design and ObservabilityTests: Evaluates understanding of distributed systems, observability, and practical approaches to tracing.

  5. Consider Guidewire's move towards cloud-native solutions. Discuss the challenges and strategies for migrating a monolithic insurance application (like an older version of PolicyCenter) to a microservices architecture running on a cloud platform like AWS or Azure. What are the trade-offs?

    Software EngineerSoftware Architecture and Cloud MigrationTests: Probes architectural thinking, understanding of microservices, and cloud migration strategies.

  6. Write a SQL query to find the top 5 insurance agents who have submitted the most new policy applications through Guidewire PolicyCenter in the last quarter, along with the total premium value for those applications. Assume tables like 'policies', 'agents', and 'policy_details'.

    Data ScientistSQL and Data AnalysisTests: Assesses SQL proficiency and ability to extract meaningful business insights from data.
