What this question tests

Ability to diagnose a metric decline rigorously and then communicate it concisely and credibly to an executive audience.

Before reporting anything, validate the drop is real: rule out a measurement or logging change, seasonality, or a definitional change in what counts as engagement.
Segment the drop by platform, region, cohort, new versus tenured, and content type, video, photo, link, to localize where it concentrates.
Correlate timing with known changes: a recent ranking update, a competitor's rise like TikTok, or a broader industry trend.
Form a leading hypothesis backed by the segmentation data, e.g. the decline concentrates in short-form video on mobile, coinciding with a ranking change on a specific date.
Structure the report top-down: headline number and business impact first, then the leading hypothesis with supporting data, then proposed next steps, not a chronological narrative.

Leads with validating the number before theorizing, stating clearly whether the drop is confirmed real or still under investigation.
Segments systematically and presents the segmentation that actually narrows the hypothesis, not a data dump.
Structures the CEO communication headline-first, matching how executives expect to receive bad news.

Presenting the CEO with an unstructured data dump or the full investigation chronology instead of a headline-first summary.
Jumping to a root cause and fix before confirming the decline is real and not a measurement artifact.

What would you say to the CEO if you don't have a confirmed root cause yet?
How would you propose fixing this if the cause turns out to be a competitor, not something Facebook controls?
