I went straight into user segmentation and kind of forgot to anchor on what problem we were actually solving.
Start by clarifying the goal and constraints, then structure your answer around user needs, data signals, and algorithmic approaches. Propose a concrete design with trade-offs, and define success metrics and potential risks.
Pro tip: Emphasize how you would balance exploration and exploitation to avoid popularity bias, and discuss how to evaluate the feature with A/B tests measuring both engagement and discovery.
Ask clarifying questions to understand the goal (e.g., increase engagement, discovery) and constraints (e.g., data availability, latency). Define what 'similar' means in terms of musical attributes, user behavior, or both.
List relevant data sources: user listening history, playlists, skips, likes, audio features (tempo, key), artist metadata, and social signals. Consider both implicit and explicit feedback.
Propose methods like collaborative filtering (user-based or item-based), content-based filtering using audio features, or hybrid models. Discuss how to handle cold start and scalability.
Describe where and how recommendations appear (e.g., artist page, radio, home). Ensure explanations are clear (e.g., 'Because you listened to X') and allow user feedback.
Specify success metrics (e.g., click-through rate, listening time, discovery rate) and how to measure them via A/B tests. Address potential biases and long-term impact.
