##### Scenario A job marketplace notices its daily application count has declined week-over-week. ##### Question What analyses and actions would you take to diagnose why application count dropped and recommend solutions? ##### Hints Evaluate funnel metrics, segment by channel/geo, check recent releases, seasonality, competitor moves, and propose experiments to address root causes.

This question evaluates a data scientist's analytical competencies in causal diagnostics, funnel and segmentation analysis, experiment interpretation, metric instrumentation, and hypothesis prioritization.

Analyze Trends to Diagnose Decline in Job Applications

Diagnose a Week-over-Week Drop in Job Applications

Scenario

A job marketplace observes that its daily application count has declined week-over-week.

Task

As the analyst on call, outline the analyses and actions you would take to:

Diagnose why application count dropped.
Identify likely root causes.
Recommend short-term mitigations and longer-term solutions, including experiments.

Clarifications and Expectations

Make and state minimal, reasonable assumptions if needed. Your response should cover:

Metric and scope clarification, and initial data-quality checks.
Funnel analysis from traffic to completed applications.
Segmentation (e.g., channel, geo, device, user cohort, job category, apply path).
Recent releases/experiments, guardrail metrics, and rollback/holdout checks.
Seasonality and external/competitor factors.
A prioritized action plan with hypotheses and proposed experiments.
