Mention specific schemas (star/snowflake), tools used, and business impact of your design decisions.
2. What's your preferred tech stack for building data pipelines, and why?
Name specific tools (dbt, Airflow, Spark, etc.), explain tradeoffs, and show awareness of scalability.
3. Describe a time when you had to debug a broken data pipeline in production. What was your approach?
Show systematic troubleshooting: monitoring alerts, log analysis, root cause identification, and prevention measures.
4. How do you ensure data quality and implement testing in your analytics workflows?
Discuss data validation rules, testing frameworks (dbt tests, Great Expectations), monitoring, and documentation.
5. Tell us about your experience with SQL optimization and performance tuning for large datasets.
Mention query profiling, indexing strategies, partitioning, materialization patterns, and specific performance improvements achieved.
6. How have you collaborated with data scientists or ML engineers on feature engineering or model pipelines?
Highlight cross-functional communication, feature store implementation, reproducibility, and how you enabled model deployment.
7. Explain your approach to designing metrics and KPIs for business stakeholders. How do you handle metric definitions?
Discuss metric layer tools (Looker, dbt metrics), governance, versioning, and aligning technical definitions with business intent.
8. What's your experience with cloud data platforms (Snowflake, BigQuery, Redshift, Databricks), and how do you decide between them?
Explain cost optimization, scalability features, integration ecosystem, and specific use cases where each excels.
9. How do you approach handling late-arriving data, slowly changing dimensions, and other common data warehouse challenges?
Discuss SCD types, event time vs processing time, backfill strategies, and idempotency in your solutions.
10. Describe your experience with AI/ML workflows: how have you prepared data for model training or prediction serving?
Cover feature pipelines, data leakage prevention, train/test split logic, model monitoring, and retraining orchestration.
11. Walk us through how you'd design an analytics architecture for a new product or business line with unclear requirements.
Show iterative approach: discovery, prototype, scalability planning, governance foundations, and flexibility for evolution.
12. Tell us about a time you had to balance technical debt with shipping new features. How did you make the decision?
Demonstrate strategic thinking: impact assessment, stakeholder communication, phased refactoring plans, and long-term vision.
