I started with demographics and quickly realized that felt too shallow for Amazon.
Start by clarifying the business goal and available data, then propose a multi-dimensional segmentation strategy that balances behavioral, demographic, and transactional factors. Emphasize how you would validate and iterate on segments using metrics like conversion and retention, and tie back to engineering considerations such as scalability and data pipelines.
Pro tip: Show awareness of Amazon's leadership principles by framing segmentation as a customer-obsession exercise that drives measurable business impact, and mention how you'd use AWS services (e.g., SageMaker, Redshift) to implement it.
Ask about the platform's goals (e.g., increase conversion, personalization) and what user data is available (e.g., clickstream, purchase history). This ensures your segmentation aligns with business needs.
Select relevant dimensions such as demographics, behavior (e.g., browsing, purchase frequency), lifecycle stage, and value (e.g., RFM). Prioritize dimensions that are actionable and data-driven.
Use clustering or rule-based methods to create initial segments, then validate with A/B tests or holdout groups to ensure they are distinct and predictive of key metrics.
Design a scalable data pipeline to assign users to segments in real-time, and set up monitoring to track segment performance and refine over time.
