What this question tests

Whether you can build a metric tree for a two-sided content platform, balancing readers and writers.

Clarify the business goal behind success here, subscription revenue growth versus content quality and engagement.
Recognize Medium's two-sided nature, readers who consume and writers who create, since both sides must succeed.
Build a metric tree: a North Star like paid subscriber retention, fed by reading time per subscriber and article completion rate.
Track writer-side health separately: articles published per month, writer retention, and earnings through the Partner Program.
Add guardrails against gaming, like read ratio and story report rate, so the metric cannot be won with clickbait.
Segment by content category and subscriber tenure to catch problems hidden inside the aggregate numbers.

Names a specific North Star, paid subscriber retention, rather than a vague catch-all like engagement.
Balances both sides of the marketplace instead of measuring only reader behavior.
Gives an illustrative number, assuming a 60 percent article completion rate as a healthy baseline.
Adds a guardrail against clickbait, such as read ratio or report rate, showing awareness that metrics can be gamed.

How would you weigh writer earnings against reader satisfaction if the two conflicted?
What would make you suspect the completion metric was being gamed?
