Technical practice
How would you turn an enterprise client's business problem into a production-ready AI architecture?
What to coverSuggested answer focus: Start with the business outcome and a measurable success criterion, then explain how you would define data flows, APIs, integrations and the technology stack. Discuss trade-offs among reliability, scalability, security, latency and cost.
How would you design and evaluate a retrieval-augmented generation pipeline?
What to coverSuggested answer focus: Explain the roles of embeddings, a vector database, retrieval and prompting. Describe how you would test whether retrieved information is relevant and whether the final answer is accurate and grounded.
When would you use an AI agent or a multi-agent workflow instead of a simpler application?
What to coverSuggested answer focus: Compare the value of delegated steps or tool use with added complexity, latency and failure modes. Explain how you would constrain, test and monitor the workflow for an enterprise use case.
How would you select an LLM or framework for an enterprise use case?
What to coverSuggested answer focus: Describe a comparison of suitable provider and open-source options against the use case's quality, privacy, latency, cost and integration needs. Explain why a small, representative proof of concept would be more useful than a choice based on a single benchmark.
What evaluation framework would you establish before deploying a GenAI application?
What to coverSuggested answer focus: Define representative test cases and measures for quality, accuracy, relevance, hallucination, latency and cost, as listed in the posting. Explain how you would compare versions and use failures to guide improvements.
How would you investigate a rise in hallucinations in a deployed RAG application?
What to coverSuggested answer focus: Separate retrieval failures from prompt, model and workflow failures using examples and evaluation results. Discuss targeted fixes and how you would verify that they improve answers without unacceptable latency or cost.
How would you build maintainable APIs and model-serving components for an AI application?
What to coverSuggested answer focus: Describe clear boundaries among pipelines, serving, APIs and integrations, with testing and validation appropriate to each. Explain how those choices support changes from prototype through production.
How would you deploy and operate an AI workload in a cloud environment?
What to coverSuggested answer focus: Discuss how containerization, CI/CD, databases and monitoring fit a deployment on AWS, Azure or GCP. Address collaboration with DevOps and cloud teams and trade-offs involving performance, availability and scalability.
What safeguards would you design for an enterprise AI application?
What to coverSuggested answer focus: Consider data privacy, unauthorised access, prompt injection, bias and hallucination—the risks named in the posting. Explain where safeguards and monitoring belong in the data flow and how you would check that they work.
How would you decide whether a GenAI proof of concept is ready for production?
What to coverSuggested answer focus: Compare the proof of concept with measurable business value and evidence from testing, validation and operational monitoring. Identify what must change in code, integrations and safeguards before deployment, and what might be reusable in a future solution.
Behavioural practice
Tell me about a time you explained a complex AI approach to a business stakeholder.
What to coverSuggested answer focus: Give the situation, the stakeholder's decision or concern, the action you took to explain trade-offs in business terms, and the result. Use a real example rather than assuming a particular client or outcome.
Describe a time you mentored engineers or improved a technical design through review.
What to coverSuggested answer focus: Set out the team's situation, your actions in a code or architecture review, and the result for delivery or engineering quality. Make your own contribution and the team's contribution clear.
Tell me about a time you coordinated with another team to move a solution into production.
What to coverSuggested answer focus: Describe the situation, what you did to resolve deployment or operational dependencies, and the result. A real example involving cloud or DevOps collaboration would connect directly to the advertised work.
Describe a time an AI proof of concept did not initially meet its success criteria.
What to coverSuggested answer focus: Explain the original goal, the evidence that exposed the gap, your actions and the result. Discuss how you balanced model quality with practical constraints such as latency or cost, if those were part of your example.
Tell me about a time you evaluated an emerging AI tool or model for a practical use case.
What to coverSuggested answer focus: Describe the situation, how you tested its usefulness, what you recommended and the result. If applicable, explain whether the work produced a reusable approach rather than implying that adoption was inevitable.
