Technical practice
How would you architect an end-to-end AI/ML pipeline from ingestion through monitoring?
What to coverSuggested preparation: Explain how ingestion, preprocessing, training, deployment and predictive analytics connect, including where you would validate data and model outputs. Discuss how you would design for maintainability, scalability and latency, which the posting explicitly emphasizes.
How would you assess whether a dataset is ready for model training?
What to coverSuggested preparation: Discuss checks for completeness, consistency and changes in data quality, then explain how findings would feed back into preprocessing. Describe how you would work with domain experts to judge whether the data represents the intended use.
How would you take an experimental model into production?
What to coverSuggested preparation: Walk through evaluating the model against business objectives, preparing a deployable artifact, testing integration and establishing monitoring. Explain the trade-offs between model performance and production constraints such as scalability and latency.
What would you include in CI/CD for an ML system?
What to coverSuggested preparation: Explain how you would test code and model-related changes before deployment, and how model versioning would support traceability or rollback. Discuss where a feature store could help keep training and production features consistent.
How would you choose an approach to reduce production inference latency?
What to coverSuggested preparation: Compare applicable options among ONNX, TensorRT, pruning and quantization, which the posting lists as examples. Explain how you would measure latency, resource use and any loss in model quality before adopting a change.
What would you monitor after deploying a predictive model?
What to coverSuggested preparation: Cover operational health, latency, input-data quality and model performance where outcomes can be measured. Explain how monitoring results would trigger investigation, retraining or a deployment decision.
How would you troubleshoot a production model that suddenly performs poorly?
What to coverSuggested preparation: Describe a systematic check of recent code or model versions, input data, preprocessing and the serving system. Explain how you would distinguish a model issue from an integration issue and communicate the impact while resolving it.
How would you make collaborative AI/ML code robust and maintainable?
What to coverSuggested preparation: Discuss testable components, clear interfaces and documentation across the pipeline. Explain how you would use GitHub-based collaboration to review changes and keep deployment-related code understandable.
How would you integrate a deployed model with an enterprise system?
What to coverSuggested preparation: Describe an API boundary, input and output validation, failure handling and deployment considerations for cloud-native services on AWS or Azure. Explain how you would balance integration reliability with inference latency.
How would you evaluate a model against business objectives and governance obligations?
What to coverSuggested preparation: Explain how you would agree on success measures during business analysis and technical design, then document model limitations and decisions. Discuss how you would identify ethical AI, governance and applicable industry-regulation concerns without assuming a specific regulation or company framework.
Behavioural practice
Tell me about a time you worked with data scientists and domain experts to operationalize a model.
What to coverSuggested preparation: Use a real situation, your specific actions to resolve differing technical and domain priorities, and the result. Focus on how collaboration changed the production design or clarified a decision.
Describe a time you supported or trained users after a technical deployment.
What to coverSuggested preparation: Set out the users' need, how you explained or documented the system, and the result. Include how you handled questions or feedback without assuming users had ML expertise.
Tell me about a time you managed several technical deliverables at once.
What to coverSuggested preparation: Explain the situation, how you prioritized work and communicated progress, and what happened. Address any trade-off you made when deadlines or dependencies competed.
Describe a production issue you resolved with another team.
What to coverSuggested preparation: Give the situation, your troubleshooting and coordination actions, and the outcome. Distinguish what you established from what you initially suspected.
Tell me about a time a business goal conflicted with a technical or governance concern.
What to coverSuggested preparation: Describe the situation, how you raised and assessed the concern with stakeholders, and the resulting decision. If relevant to your real example, explain how you documented the trade-off or adjusted the design.
