Product design question

How would you increase the frequency of YouTube (visits/week/user)?

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

Habit formation and engagement product sense, distinguishing frequency from total watch time.

Clarify the goal: visits per week per user, a frequency metric, not total watch time, so the fix should target return triggers, not session length.
Segment users by current visit frequency: daily visitors, a few times a week, and less than weekly.
Focus on the few times a week segment, since they're closest to becoming daily habitual users.
Identify a gap: users without a strong notification habit miss new content from channels they already like.
Propose a personalized digest notification sent at a user's typical active time, summarizing new videos from subscribed channels plus one recommended discovery.
Define success as visits per week per user in the target segment, watching for notification fatigue via opt out rate.

Targets the exact metric asked, visits per week, rather than drifting into watch time or engagement generally.
Segments by current frequency and picks the most winnable group instead of targeting everyone equally.
Gives an illustrative number, for example assuming visits per week rise from 3 to 4 for the targeted segment.
Explicitly tracks a guardrail, notification opt out rate, to avoid trading frequency for annoyance.

Proposing changes aimed at session length or watch time instead of visit frequency, the actual metric asked about.
Ignoring notification fatigue as a real risk of a frequency focused push strategy.

How would you personalize notification timing without being intrusive?
How would you know if a frequency increase was healthy versus just notification driven and not sticky?
