Metrics question

You are the PM of Facebook Lite. What goals would you set?

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Understanding a product built for a specific constrained context, low bandwidth and low end devices, and setting fitting goals.

State the product's purpose, serving users on slow networks and low end devices, mostly in emerging markets, with a lightweight app.
Set a primary goal tied to that mission, reducing data usage per session while maintaining core engagement.
Set a growth goal specific to the underserved segment, growth in first time internet users onboarded through this app.
Set a guardrail goal, crash rate and load time on low end devices, since performance is the entire value proposition.
Avoid copying the main app's goals, since the users and constraints here are fundamentally different.

Anchors goals in the specific mission, low data and low end device performance, rather than generic engagement or revenue goals borrowed from the main app.
Sets a measurable data efficiency goal, reducing megabytes per session by a stated percentage while keeping session length stable.
Names a guardrail specific to the context, crash rate on very low cost devices, since a general crash rate metric could hide the real user pain.

Setting the same goals as the main app, ignoring this product's distinct purpose and users.
Focusing only on growth with no performance or data efficiency goal.
No device or network specific guardrail metric.

How would you balance adding features against keeping the app lightweight?
How would you measure success differently across regions with varying network quality?
