Share a time when you had to explain a complex technical issue to a non-technical stakeholder.
Describe how Adidas could use S3 and Athena to analyze clickstream data.
Explain how to implement schema validation for incoming data streams.
Propose a solution for monitoring and maintaining data quality across multiple regions.
What's your approach to continuous learning, especially in evolving data technologies?

Write a Python script to process raw JSON files containing sales data and load them into a relational database.
Discuss a project where you balanced business goals with technical constraints.
Walk through a production incident where data freshness or correctness was at risk. How did you balance immediate mitigation vs. root-cause remediation? What architectural changes would prevent recurrence, and what are the cost vs. reliability trade-offs?
Design a star schema for retail analytics (e.g., Adidas). Explain the dimensional modeling choices, SCD strategy, and how you would scale this schema for global multi-currency, multi-region deployments. What are the refresh and storage cost implications?
Explain how partitioning and bucketing in Hive/Spark optimize queries. What are the trade-offs in bucket count, partition cardinality, and small-file problem? When does over-partitioning or over-bucketing become counterproductive?
Explain the differences between OLTP and OLAP databases and their relevance in Adidas's operations.
How would you create a materialized view for frequently accessed aggregated sales data?
How would you handle duplicate or corrupted data in a batch ETL job?
How would you optimize a query fetching sales data across multiple countries with billions of rows?

What are the benefits of using a cloud data warehouse (e.g., Redshift, Snowflake) for analytics?
Write a query to calculate the total revenue generated by each product category.
Write a query to find the top 5 most-sold Adidas products in the last month.
