Technical practice
How would you design retrieval for an enterprise AI feature?
What to coverThe role includes building AI systems across retrieval and workflow integration. Suggested preparation: explain how content becomes retrievable, how relevant results reach an LLM, and how you would check whether the answers are useful.
How would you troubleshoot poor results from a vector-based retrieval workflow?
What to coverVector workflows are listed as preferred experience. Suggested preparation: distinguish retrieval failures from answer-generation failures, then discuss how you would inspect retrieved results and weigh changes to the retrieval approach.
How would you structure and improve a prompt workflow?
What to coverThe posting highlights prompt workflows and prompt orchestration. Suggested preparation: describe how you would manage inputs, retrieved context and outputs, and how you would test a prompt change before adopting it.
How would you expose an LLM-backed feature through a product API?
What to coverThe role calls for model integration, strong API discipline and scalable product environments; FastAPI is highlighted. Suggested preparation: discuss interface design, request and response handling, failure behaviour, and where framework choices affect maintainability.
How would you design data flow between an AI service and an existing product system?
What to coverStrong knowledge of data flow and scalable service integration is a minimum qualification. Suggested preparation: explain system boundaries, how information moves through the feature, and trade-offs between tighter integration and independent services.
How would you integrate an intelligent feature into a broader workflow?
What to coverWorkflow integration and practical enterprise features are explicit responsibilities. Suggested preparation: describe where an AI step adds value, what happens when it cannot produce a useful result, and how the surrounding workflow remains dependable.
How would you evaluate whether an AI feature improves product usefulness?
What to coverThe role involves product quality and usefulness, and model evaluation is preferred exposure. Suggested preparation: propose representative test cases, explain how you would assess output quality, and distinguish model behaviour from end-to-end product outcomes.
What would you observe when troubleshooting a production AI feature?
What to coverThe posting calls for observable, production-aware engineering. Suggested preparation: discuss how you would trace a request through retrieval, model integration and the product workflow while balancing diagnostic value against sensitive-data exposure.
How would you account for security in a retrieval-backed AI feature?
What to coverSecure AI engineering is an explicit responsibility. Suggested preparation: discuss risks around access to retrieved content and data passed to models, and explain how security decisions interact with usefulness and maintainability.
What would you consider when delivering an AI service in a cloud-hosted product environment?
What to coverCloud-hosted AI service delivery and productionization are preferred areas of knowledge. Suggested preparation: compare deployment and operational trade-offs, including scalability, failure handling and the ability to maintain the service over time.
Behavioural practice
Tell me about a time you worked with product and platform teams to improve a feature.
What to coverCollaboration to improve quality, usefulness and maintainability is part of this role. Suggested preparation: use a real situation, your specific actions with each team, and the resulting product or engineering outcome.
Describe a time you coordinated technical delivery across teams in different locations.
What to coverThe role sits in a connected U.S. and India product engineering structure. Suggested preparation: give the situation, how you kept decisions and handoffs clear, and the result without assuming any particular working arrangement at Willsfly.
Give an example of a technical decision where you balanced immediate delivery with maintainability.
What to coverThe posting emphasizes architecture-conscious execution and long-range software continuity. Suggested preparation: describe the situation, alternatives you considered, the action you took, and what happened afterward.
Tell me about a time you investigated a quality problem in a deployed software feature.
What to coverQuality, observability and production-aware engineering are stated priorities. Suggested preparation: explain the situation, how you identified the cause and worked toward a fix, and the measurable or observable result.
Describe a time you kept a complex engineering deliverable on track while requirements evolved.
What to coverThe role calls for structured enterprise engineering and delivery accountability. Suggested preparation: recount the situation, how you clarified priorities and communicated decisions, and the result of your actions.
