Technical practice
How would you incorporate a generative AI model into a production application?
What to coverSuggested preparation: Explain how the model would fit into the application and its pipeline, from inputs through outputs. Discuss how you would test whether the resulting system meets its intended use before deployment.
How would you evaluate a generative AI solution?
What to coverSuggested preparation: Describe how you would choose evaluation criteria for the application's goal and examine output quality and reliability. Explain what evidence would prompt you to revise the model integration or surrounding application.
How would you design a production-level AI pipeline?
What to coverSuggested preparation: Walk through the stages needed to prepare inputs, run a model and deliver outputs in a deployable application. Address how you would identify bottlenecks and make the pipeline dependable as usage grows.
What would influence your choice between cloud and on-premises deployment?
What to coverSuggested preparation: Compare the environments in terms of application needs, scalability, operational constraints and integration with the pipeline. Explain how you would validate that the chosen deployment remains production-ready.
How would you diagnose a deployed model whose performance has declined?
What to coverSuggested preparation: Explain how you would distinguish a change in model results from a pipeline or deployment problem. Describe the evidence you would gather before choosing a model, pipeline or deployment change.
How do neural network architecture and deep learning framework choices affect an AI application?
What to coverSuggested preparation: Relate architecture choice to the task and the data rather than naming a framework without context. Discuss trade-offs that matter when implementing and deploying the model.
How would you design and assess a chatbot?
What to coverSuggested preparation: Describe how you would define its intended interactions, handle unclear requests and assess response quality. Connect those decisions to integrating the chatbot into an application; the posting names chatbot development as an area of familiarity.
How would you approach an image-processing component in an AI solution?
What to coverSuggested preparation: Explain how you would prepare image inputs and check whether the component performs its intended task. Discuss how image quality or processing demands could affect the wider pipeline; the posting names image processing as an area of familiarity.
How would you improve scalability without losing model quality?
What to coverSuggested preparation: Describe how you would locate capacity or latency constraints in the application and pipeline. Explain how you would compare deployment or pipeline changes against their effects on model results.
Behavioural practice
Tell me about a time you aligned an AI implementation with a cross-functional project goal.
What to coverSuggested preparation: Use a real example with the situation, your actions to clarify goals and coordinate with others, and the result. Be specific about how the collaboration affected the technical approach.
Describe a project problem you resolved while working independently.
What to coverSuggested preparation: Give the situation, what you investigated and decided yourself, and the result. Explain when you sought input and how you shared what you learned, reflecting the role's expectation of independent work and subject-matter expertise.
Tell me about a team discussion in which you helped improve a model or deployment strategy.
What to coverSuggested preparation: Describe the situation, the evidence or trade-off you contributed, and the result of the discussion. Distinguish your contribution from the team's eventual decision.
Describe a time you documented a technical process for others.
What to coverSuggested preparation: Set out the situation, what you documented and how you shared it, and the result. Explain how you checked whether the documentation supported team continuity or understanding.
Tell me about a time you guided a junior team member on a technical practice.
What to coverSuggested preparation: Use a real situation, the guidance you gave and the result. Explain how you adapted your support to the person's needs without taking over their work.
