What this question tests
Metrics design for a new ephemeral content format: can you define metrics specific to audio only stories rather than reusing video story metrics.
How to approach it
- State the goal: give users a lower effort, more intimate way to share to stories without being on camera.
- Set the primary metric as number of audio posts created per active user per week, since creation supply is usually the bottleneck for a new format.
- Add a listener side metric, completion rate of audio plays, since audio needs to hold attention without visuals to prove the format works.
- Add a guardrail, drop off from story viewing overall, to check whether audio posts get skipped more than video ones, hurting the broader story experience.
- Compare adoption against existing text and photo story posts to see if audio fills a real gap or just adds friction.
- Define success as sustained posting rate after the first use, not just initial trial.
What a strong answer includes
- Picks creation supply as the north star, recognizing a new content format lives or dies on whether people keep posting it.
- Adds a specific guardrail, skip rate within stories, that a generic engagement metric would miss.
- Compares against existing formats to test whether audio adds incremental value or just fragments attention.
Common mistakes
- Reusing video story metrics wholesale without adjusting for audio's different consumption pattern.
- Measuring only initial trial and not repeat posting, which is the real signal of format fit.
Likely follow-up questions
- How would you know if audio posts are cannibalizing video posts?
- What would make you kill this format after a few months?
