Technical practice
How would you take an ML model from development to a highly available production service?
What to coverSuggested preparation: Describe the pipeline stages, how data scientists and engineers would hand off work, and how you would make deployment repeatable. Explain trade-offs between availability, performance, and operational complexity; the posting specifies the goals, not a particular architecture.
How would you design CI/CD for AI/ML models?
What to coverSuggested preparation: Cover validation of data, code, and model behavior before release, along with versioning and a way to recover from a problematic deployment. Distinguish model-specific checks from conventional software tests without assuming a particular CI/CD tool.
How would you build and evaluate a RAG pipeline using vector search and an LLM?
What to coverSuggested preparation: Explain ingestion, retrieval, response generation, and how you would assess retrieval quality and answer reliability. Discuss latency and quality trade-offs; RAG, vector search, and LLM pipelines are named responsibilities.
When would an agentic AI pipeline be preferable to a simpler LLM workflow?
What to coverSuggested preparation: Compare the value of multi-step actions with added complexity and failure modes. Explain how you would evaluate outputs and limit unsafe actions; these are preparation considerations, not specified implementation requirements.
How would you diagnose and improve a slow Spark workload on Databricks?
What to coverSuggested preparation: Walk through evidence you would inspect before changing partitioning, joins, or data layout, and explain the likely trade-offs. Spark, Databricks, and distributed computing are listed in the requirements; no particular workload is specified.
How would you structure SQL data models and Delta Lake data for reliable ML pipelines?
What to coverSuggested preparation: Discuss data quality, changing inputs, and choices that affect downstream queries and model reproducibility. Explain how you would validate the design rather than assuming a particular schema or data volume.
How would you use Unity Catalog while addressing governance, compliance, and ethical AI?
What to coverSuggested preparation: Explain how you would reason about access to data and models, traceability, and review of potentially harmful outcomes. The posting names Unity Catalog and these governance goals but does not specify a regulatory framework.
How would you provision a secure cloud ML environment using infrastructure as code?
What to coverSuggested preparation: Choose one listed cloud platform and a relevant listed IaC option, then explain access controls, change review, and repeatable deployment. Discuss security versus delivery speed without assuming a mandated cloud or template tool.
How would you investigate a production pipeline whose performance degrades in real time?
What to coverSuggested preparation: Distinguish data, model, retrieval, and infrastructure signals, then describe how you would isolate the cause and decide whether to intervene. Tie the response to the posting’s monitoring, optimization, and high-availability responsibilities.
How would you weigh performance and cloud cost in a hybrid-cloud ML design?
What to coverSuggested preparation: Compare placement, data movement, operational complexity, and cost against performance needs. Hybrid-cloud experience and cloud cost optimization are preferred, so treat this as a trade-off exercise rather than an assumed project.
Behavioural practice
Tell me about a time you aligned customer architects, data scientists, and engineers to put a model into production.
What to coverSuggested preparation: Use a real situation, your specific actions to resolve differing priorities, and the result. This reflects the posting’s cross-functional, client-facing production work.
Describe a time you explained a complex AI or data-platform decision to non-technical stakeholders.
What to coverSuggested preparation: Set out the audience and decision, how you adapted your explanation, and what resulted. Focus on clarity and honest treatment of trade-offs rather than claiming a particular client outcome.
Tell me about a time you managed a difficult technical relationship with a customer or partner.
What to coverSuggested preparation: Give the situation, the actions you took to establish expectations or address disagreement, and the result. Customer and partner relationships are explicit requirements.
Describe a production reliability issue that required coordination across teams.
What to coverSuggested preparation: Explain the situation, your role in diagnosis and communication, and the result, including what changed afterward if applicable. Choose a real example relevant to the posting’s monitoring and high-availability work.
Tell me about a time a governance or security concern conflicted with a delivery goal.
What to coverSuggested preparation: Describe the situation, how you evaluated the risk and worked with others, and the result. The role calls for cloud security, compliance, governance, and ethical AI, without naming a specific policy or regulation.
