Summary

LinkedIn PM interview with a classic metrics/troubleshooting question about mobile installs dropping. Pretty short session from what I could tell, just the one scenario but it went pretty deep.

Questions Asked (1)

Q1

LinkedIn's iOS app installs are down. How do you investigate and respond?

I jumped straight into the metrics funnel which felt right but I skipped clarifying the timeframe and magnitude first, which I think cost me points early on.

Suggested Approach

Start by clarifying the scope and impact of the decline, then systematically investigate potential causes across the funnel, technical, and external factors. Prioritize hypotheses based on data, and propose a response plan that includes immediate mitigation and long-term prevention.

Pro tip: Demonstrate a structured, data-driven approach by mentioning specific metrics you'd check (e.g., conversion rate by channel, crash rates) and by considering both internal and external factors. Also, show awareness of LinkedIn's ecosystem and how app installs tie to broader business goals.

1. Clarify and Scope

Define what 'down' means: magnitude, timeframe, and affected segments (e.g., iOS only, specific regions). Confirm data sources and ensure the decline is real and not a tracking issue.

2. Segment and Funnel Analysis

Break down the install funnel (impressions, app store views, downloads) and segment by channel, geography, device, and user cohort to isolate where the drop occurs.

3. Generate and Prioritize Hypotheses

List potential causes: technical (app crashes, compatibility), marketing (campaign changes, budget cuts), external (competitor launch, iOS updates), and product (onboarding changes). Prioritize based on impact and likelihood.

4. Investigate and Validate

Use data to test hypotheses: check crash logs, campaign performance, app store rankings, and user feedback. Collaborate with engineering, marketing, and data teams to validate root cause.

5. Respond and Monitor

Implement immediate fixes (e.g., rollback, campaign adjustments) and long-term solutions (e.g., improved testing, monitoring). Set up alerts and track recovery metrics to ensure sustained improvement.

Key Points to Mention

  • Define clear success metrics for app installs (e.g., install rate, cost per install) and set up dashboards for real-time monitoring.
  • Consider both internal factors (e.g., recent app updates, marketing campaigns) and external factors (e.g., iOS updates, competitor activity).
  • Use cohort analysis to see if the decline is uniform or specific to certain user segments.
  • Collaborate cross-functionally with engineering, marketing, and data science teams to diagnose and resolve.
  • Prioritize fixes based on impact and effort, and communicate transparently with stakeholders.
  • Implement a post-mortem to prevent future occurrences and improve processes.
