This one took me a second because it sounds like a simple yes/no product call but there's actually a lot underneath it.

Suggested Approach

Start by clarifying the goal of the split—likely to improve user experience and engagement—and then evaluate the trade-offs through a structured framework that includes user research, data analysis, and experimentation. Propose a hypothesis-driven approach: define success metrics, segment users, and design A/B tests to measure impact before a full rollout.

Pro tip: Emphasize that any major change to Feed must be tested incrementally and consider network effects—what works for one user segment might harm the overall ecosystem. Also, highlight the importance of balancing short-term metrics with long-term user satisfaction and platform health.

1. Clarify Objectives & Hypotheses

Define what problem the split aims to solve (e.g., information overload, declining friend interactions) and form hypotheses about how separate tabs would improve user experience and engagement.

2. Conduct User Research & Data Analysis

Gather qualitative insights (surveys, interviews) and quantitative data (engagement metrics, content consumption patterns) to understand user needs and current pain points.

3. Define Success Metrics & Guardrails

Identify key metrics (e.g., time spent, friend interactions, content diversity) and guardrail metrics (e.g., overall DAU, user satisfaction) to evaluate the split's impact.

4. Design & Run A/B Tests

Create controlled experiments to test the split with a subset of users, measuring both intended outcomes and unintended consequences across different user segments.

5. Analyze Results & Decide on Rollout

Evaluate test results against success metrics, consider scalability and network effects, and decide whether to launch, iterate, or abandon the split.

Key Points to Mention

  • User segmentation: different users have different needs (e.g., casual vs. power users, age groups).
  • Trade-offs: potential decrease in serendipitous discovery vs. increased friend-focused engagement.
  • A/B testing methodology: randomization, control groups, statistical significance, and avoiding novelty effects.
  • Network effects: how changes affect content creators, advertisers, and the overall ecosystem.
  • Long-term vs. short-term metrics: ensuring the change doesn't harm long-term retention or satisfaction.
  • Alternative solutions: consider less disruptive options like algorithmic adjustments or UI tweaks before a full split.
