Introduction
Facebook's News Feed is a feature I particularly appreciate. It's the core of the Facebook experience, aggregating and displaying content from friends, pages, and groups. To improve it, I'd focus on enhancing personalization and reducing content fatigue. Let me outline my approach to this product improvement challenge.

Clarifying Questions (5 mins)
Why this matters: Understanding current performance baselines helps set improvement goals. Hypothetical answer: Daily active users (DAU) engaging with News Feed is 1.5 billion, with an average session time of 30 minutes. Impact: This data will help quantify the potential reach and impact of improvements.
Why this matters: Identifying pain points directly from users guides improvement efforts. Hypothetical answer: Users report seeing too much irrelevant content and missing important updates from close friends and family. Impact: This insight will shape our focus on personalization and content relevance.
Why this matters: Aligning improvements with broader company goals ensures strategic relevance. Hypothetical answer: Facebook is planning to increase focus on community-building and meaningful interactions. Impact: Our improvements should prioritize fostering connections and engagement within communities.
Why this matters: Understanding technical boundaries helps propose feasible solutions. Hypothetical answer: The current architecture can handle real-time updates but struggles with complex, multi-factor personalization at scale. Impact: We'll need to consider scalability and performance in our proposed improvements.
Based on these answers, I'll assume that our primary goal is to increase user engagement and satisfaction with News Feed by improving content relevance and fostering meaningful interactions, while working within current technical constraints.
