Technical practice
How would you turn an ambiguous customer problem into an AI solution architecture?
What to coverSuggested preparation: Explain how you would clarify the business objective, users, constraints and success criteria with customer engineering and business teams. Describe how those findings would shape a practical architecture and a bounded proof of concept.
How would you design a RAG application for use in a customer environment?
What to coverSuggested preparation: Walk through document preparation, retrieval, context assembly and answer generation, including where a vector database might help. Discuss how you would test retrieval quality and handle missing or conflicting source material.
How would you build a multi-step agentic workflow that calls tools?
What to coverSuggested preparation: Explain how orchestration and tool or function calling would manage state and sequence steps. Address tool permissions, input validation and when the workflow should stop or fail safely.
How would you structure the Python services and APIs around an LLM application?
What to coverSuggested preparation: Describe service boundaries, API contracts, testing and deployment considerations for a production application. Explain when a separate microservice is useful and when it adds unnecessary operational complexity.
What would you change when moving an AI proof of concept into production?
What to coverSuggested preparation: Contrast a demonstration with a deployable system in a customer environment, including access controls, repeatable deployment and operational ownership. Explain how you would verify readiness before rollout rather than assuming a successful proof of concept is sufficient.
How would you design retries, fallbacks and safe failure for an LLM workflow?
What to coverSuggested preparation: Distinguish transient failures from errors that should not be retried, particularly around tool calls. Discuss timeouts, bounded retries, fallback behaviour and what the user or operator should see when the workflow cannot complete.
What would you monitor in a deployed AI application?
What to coverSuggested preparation: Cover logs and operational signals that help diagnose failures across APIs, retrieval, model calls and tools. Explain how you would balance diagnostic value with the need to protect customer data.
How would you evaluate whether a GenAI application is ready for rollout?
What to coverSuggested preparation: Describe task-relevant test cases and how you would assess output quality, failure modes and changes between versions. Explain how evaluation results and production monitoring would inform a rollout decision.
How would you improve latency, scalability and cost without undermining answer quality?
What to coverSuggested preparation: Identify likely bottlenecks across retrieval, model calls, tool execution and service infrastructure. Explain how you would measure each change and make the quality-versus-speed-or-cost trade-off visible.
How would you choose deployment components for a customer's AI environment?
What to coverSuggested preparation: Compare practical choices for cloud services, application frameworks and supporting infrastructure against the customer's constraints. Treat Azure, AWS, GCP and the listed AI frameworks as possible options, not as a required stack.
Behavioural practice
Tell me about a time you clarified an ambiguous request with a customer or partner team.
What to coverSuggested preparation: Use a real situation to show which questions you asked, how you reconciled different needs and what you agreed to deliver. State the result and what changed because of that discovery work.
Describe a time you communicated a technical risk or trade-off to a non-technical stakeholder.
What to coverSuggested preparation: Give the situation, the decision at stake and the action you took to explain the options plainly. Describe the resulting decision or next step without overstating your individual impact.
Tell me about a cross-functional delivery problem you helped resolve.
What to coverSuggested preparation: Choose an example involving distinct technical or product perspectives and explain your role, the actions you took and the outcome. Focus on how you handled dependencies or disagreement rather than claiming sole ownership of a team result.
Describe a rollout where adoption or operational handover needed attention.
What to coverSuggested preparation: Explain the situation, what you did to support users or the receiving team, and what documentation or support arrangements mattered. State the observed result, including any remaining issues.
Tell me about a time you helped another engineer improve a production practice.
What to coverSuggested preparation: Use a real example to describe the practice, your mentoring action and its result. Keep the focus on what the engineer or team could do differently afterward.
