Architect a Multi-Touch Attribution System
This tests your grasp of modern data challenges like signal loss. A good answer discusses data ingestion, identity resolution, and model trade-offs. A red flag is focusing only on the algorithm and ignoring the data pipeline's fragility.
This question tests your awareness of modern data realities, especially signal loss from privacy changes. A strong answer outlines a pipeline for ingestion, identity resolution, and modeling, then contrasts simple (last-touch) vs. complex (time-decay) models by their implementation costs and biases. A major red flag is ignoring the 30-60% signal loss and the difficulty of identity resolution, focusing only on the attribution algorithm itself.
