Technical practice
How would you design an end-to-end ML pipeline for a production customer workload?
What to coverSuggested preparation (inferred): Explain how you would connect feature engineering, training, experiment tracking, serving and monitoring on a unified platform. Address reproducibility, deployment reliability and where you would place checks before a model reaches production.
How would you integrate a deployed ML application with cloud-native services?
What to coverSuggested preparation (inferred): Describe the infrastructure and operational boundaries you would consider on AWS, Azure or GCP. Discuss trade-offs involving scaling, access control and maintainability without assuming a particular customer architecture.
How would you detect and respond to drift in a production model?
What to coverSuggested preparation (inferred): Distinguish changes in input data from changes in model performance, and explain what you would monitor when labels arrive late. Describe how findings could trigger investigation, retraining or another response rather than an automatic change.
How would you optimize training and inference for an ML or AI workload?
What to coverSuggested preparation (inferred): Explain which measurements you would establish before changing a workload, such as training time, inference latency, throughput and cost. Discuss how an optimization might improve one measure while affecting model quality or reliability.
How would you design and evaluate a retrieval-augmented generation application?
What to coverSuggested preparation (inferred): Walk through document preparation, vector retrieval, context selection and answer generation. Explain how you would test retrieval quality separately from answer quality and handle responses without adequate supporting context.
When would you consider LLM fine-tuning instead of retrieval for a customer use case?
What to coverSuggested preparation (inferred): Compare what each approach changes and the evidence you would seek before choosing one. Address data requirements, evaluation, updating information and deployment complexity rather than presenting either approach as universally better.
How would you design a tool-calling agent, and when would multi-agent orchestration be warranted?
What to coverSuggested preparation (inferred): Explain tool selection, state handling, permissions and guardrails for an agent that can take actions. Compare a simpler single-agent design with multi-agent orchestration in terms of coordination, observability and failure modes.
How would you enable natural-language queries over structured enterprise data?
What to coverSuggested preparation (inferred): Discuss how a system could map user intent to the right data and produce a verifiable answer. Address ambiguity, access controls and checks against incorrect queries or misleading results.
How would you evaluate and monitor a production generative AI application?
What to coverSuggested preparation (inferred): Describe a mix of task-specific quality checks, safety checks and operational signals. Explain how traces or other observations would help diagnose whether a failure came from retrieval, an agent action or model output.
How would you support a Solution Architect in a technical discussion about model serving?
What to coverSuggested preparation (inferred): Show how you would clarify the customer's workload, success criteria and current constraints before proposing an architecture. Discuss serving and monitoring trade-offs in terms a technical buyer could use to evaluate a production design.
Behavioural practice
Tell me about a time you worked with another technical lead to resolve a customer's architecture concern.
What to coverSuggested practice (inferred): Use a real situation, explain your actions and collaboration, and state the result. Focus on how you clarified the concern and handled any technical trade-offs rather than claiming a particular sales outcome.
Describe a time you explained a complex ML or AI concept to people with different technical backgrounds.
What to coverSuggested practice (inferred): Give the situation, how you adjusted your explanation or teaching approach, and the result. Include how you checked understanding without overstating the audience's prior knowledge.
Tell me about a time you represented customer needs to a product or engineering team.
What to coverSuggested practice (inferred): Describe the situation, the evidence you gathered, the action you took and the result. Explain how you handled competing priorities without implying you controlled the product roadmap.
Describe a time you mentored a colleague or shared technical expertise across a team.
What to coverSuggested practice (inferred): Set out the situation, what you did to make the knowledge useful, and the result. Note how you adapted to the colleague's needs and what feedback showed whether the approach helped.
Tell me about a time you had to learn an unfamiliar AI or ML technique to address a practical need.
What to coverSuggested practice (inferred): Explain the situation, how you evaluated and applied the technique, and the result. Connect the learning to a measurable technical or business need, while acknowledging what remained uncertain.
