← Walmart Labs Interview Insights
I jumped straight into segmenting by risk groups, which felt right, but I spent too long on the framework and not enough time actually defending my prioritization logic.
Start by clarifying the goal and constraints: are we optimizing for equity, speed, or maximum impact? Then propose a phased allocation framework based on risk and exposure, using data to prioritize groups, and outline a distribution plan with clear metrics and feedback loops.
Pro tip: Acknowledge the ethical and political dimensions of vaccine allocation, and show how you'd communicate transparently with stakeholders to build trust. This demonstrates maturity beyond pure analytics.
Ask questions to understand the primary goal (e.g., reduce mortality, stop transmission) and constraints (e.g., vaccine type, storage, time). This ensures your approach aligns with stakeholder priorities.
Establish criteria such as risk of exposure (healthcare workers), risk of severe outcomes (elderly, comorbidities), and equity (underserved communities). Use a scoring model to rank groups.
Divide the population into priority tiers based on criteria, then allocate the 5,000 doses proportionally or sequentially. For example, start with 2,000 to healthcare workers, 2,000 to elderly, 1,000 to essential workers.
Plan how to reach each group: use existing healthcare infrastructure, mobile units, or community centers. Consider cold-chain requirements and accessibility.
Set up metrics (e.g., doses administered, coverage per group) and gather feedback. Communicate transparently about decisions and adjust as new data emerges.
