Technical practice
How would you scope a data science project that spans business functions and countries?
What to coverThe role leads projects from concept through delivery across GCPL functions and geographies. Suggested preparation: explain how you would define the decision, align stakeholders on outcomes, assess data availability and set delivery milestones.
How would you investigate conflicting or incomplete data from several sources?
What to coverThe analytics team analyzes diverse data sources, and the role calls for SQL or other programming skills and statistical analysis. Suggested preparation: describe checks for definitions, missingness and consistency before combining data or drawing conclusions.
How would you review a predictive model before business sign-off?
What to coverThe posting explicitly names evaluation metrics, robustness, leakage and business sign-off. Suggested preparation: discuss a suitable baseline, validation design, error analysis and how you would explain the model's limitations to decision-makers.
How would you approach a time-series forecasting problem for an FMCG decision?
What to coverThe posting mentions time-series forecasting and exposure to TensorFlow, PyTorch or Keras. Suggested preparation: compare simple baselines with more complex models, use time-aware validation and explain when added complexity would not be worthwhile.
What would you consider when deploying and monitoring a model on a cloud ML platform?
What to coverThe role cites AWS, GCP or Azure and MLOps practices including deployment, monitoring, versioning and automation. Suggested preparation: cover reproducibility, production reliability, performance monitoring and how you would respond to degradation.
How would you define KPIs and determine whether an analytics initiative improved outcomes?
What to coverThe role establishes metrics, tracks project impact and recommends adjustments. Suggested preparation: distinguish model metrics from business outcomes, establish a baseline and discuss attribution limits before claiming an improvement.
How would you turn a model into a dashboard or operational product?
What to coverThe posting calls for models embedded in business products or dashboards and for actionable recommendations. Suggested preparation: explain how users would act on outputs, what context and limitations they need, and how you would check whether the product is used.
How would you design and evaluate a RAG workflow for business documents?
What to coverThe posting names embeddings, large text corpora and RAG pipelines for LLM-driven workflows. Suggested preparation: address retrieval quality, grounding, access controls and evaluation of answers rather than assuming fluent output is correct.
What safeguards would you use for generative SQL over structured business data?
What to coverGenerative SQL query development is an example given in the posting. Suggested preparation: discuss schema context, permission boundaries, query validation and checks that generated results answer the intended question.
When would an agentic AI workflow be preferable to a simpler automated workflow?
What to coverThe posting mentions agentic frameworks for complex, multi-step business processes. Suggested preparation: compare flexibility with complexity and explain how you would constrain actions, handle failures and evaluate whether the workflow delivers value.
Behavioural practice
Tell me about a cross-functional project you owned from concept to delivery.
What to coverThe role requires end-to-end ownership across business and technology stakeholders. Suggested preparation: use a real situation, the actions you took to align objectives and deliver the work, and the result; distinguish your contribution from the team's.
Describe a time you resolved a blocker involving stakeholders with different priorities.
What to coverThe posting explicitly calls for resolving blockers in cross-functional delivery. Suggested preparation: describe the situation, how you surfaced and negotiated the trade-off, and what changed as a result.
Tell me about a time you managed an external analytics partner's delivery.
What to coverVendor management against quality, timeline and budget expectations is a stated responsibility. Suggested preparation: give a real situation, the actions you took to set expectations and address issues, and the delivery result.
Describe a time you helped a junior data scientist improve their work.
What to coverThe role includes mentoring on execution, technical development and career growth. Suggested preparation: explain the situation, your specific coaching actions and the observable result without overstating your role.
Tell me about a time you changed an analytical recommendation after stakeholder feedback or new evidence.
What to coverThe role calls for actionable insights, communication with non-technical stakeholders and adjustments based on results. Suggested preparation: describe the initial situation, how you evaluated and communicated the new information, and the resulting decision or outcome.
