Metrics question

What would you define as the goals for Facebook's new user experience?

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

Tests defining onboarding-stage goals that connect early actions to long-term retention rather than measuring signups alone.

Clarify the goal: a new user experience should get people to a meaningful first value moment quickly, not just complete signup steps.
Identify the aha moment: connecting with a critical mass of real friends or groups relevant to their interests within the first session.
Set the north star as activation rate, percent of new users reaching a defined threshold, like connecting with 10 friends or joining 2 groups within 7 days.
Add a guardrail on time-to-first-value, since a slow or confusing onboarding flow risks early drop-off before the aha moment is reached.
Define long-term success by correlating activation against 30-day retention, since the real test is whether onboarding predicts lasting engagement.

Defines a concrete activation threshold, like a friend or group count, instead of a vague get-people-started answer.
Explicitly links the onboarding metric to downstream 30-day retention, proving the activation definition actually matters.
Separates speed to value, time-to-first-value, from the completion of onboarding steps alone.

Measuring only signup completion rate without any activation or retention link.
Picking an activation threshold with no data or reasoning behind why that specific number matters.

How would you determine the right friend or group count to define activation?
How would you handle users who don't have many existing Facebook friends to connect with?
