The brief

A global video-streaming service has saturated its core markets — subscriber growth has stalled and churn is rising. Leadership has relied on subscriber adds as the headline metric; now the game is retention, engagement, and revenue per user. You're asked how the strategy should change and where to focus.

How to approach it

  1. Reframe the success metric — from net adds to engagement, retention, and ARPU
  2. Diagnose churn drivers — content gaps, price sensitivity, password sharing, competition
  3. Evaluate levers — ad-supported tier, password-sharing crackdown, content efficiency, bundling
  4. Weigh content spend ROI — is more spend buying retention, and where
  5. Recommend a focused set of moves with the trade-offs (e.g. ads vs premium positioning)

What a strong answer does

  • Shifts the goal from subscriber growth to engagement-driven retention and ARPU
  • Treats content spend as an investment to be measured on retention, not volume
  • Weighs the ad-tier / sharing-crackdown trade-offs against brand and churn
  • Connects engagement (hours, completion) to retention causally
  • Prioritizes a few high-impact moves over doing everything

Red flags interviewers score down

  • Keeps chasing subscriber adds in a saturated market
  • Treats content spend as inherently good with no ROI link
  • Recommends an ad tier or sharing crackdown without weighing churn/brand risk
  • Ignores engagement as the leading indicator of retention
