Design an Adaptive Home Screen for a Streaming Recommender
Overview
What this challenge is about.
Build three adaptive layouts from session signals, prototype in React, and analyze A/B test results. Earn a verifiable certificate.
The scenario
Lumora is a venture-backed, ad-supported streaming startup whose free tier drives most of its 6 million monthly viewers, so every additional title-click is ad inventory and the home screen is the single highest-traffic surface in the product.
The Brief
What you'll do, and what you'll demonstrate.
Lift home-screen click-through rate from 4.2 percent to 6 percent by adapting the layout to each session's viewing intent, without changing the underlying recommender model.
Earning criteria — what you'll demonstrate
- Translate behavioral session signals into a defensible intent classification that drives interface adaptation
- Engineer interface transitions that change layout without flicker, layout shift, or loss of scroll context
- Design a properly powered, pre-registered controlled experiment with correct segmentation
- Read segmented experiment results and convert them into a single, justified ship decision
- Communicate a roll-out plan that names the risks and the reversal path before launch

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Frontend Engineer, Personalization
This challenge mirrors the core personalization-team task of reshaping a high-traffic surface around user intent without touching the model, building the adaptive interface and proving it with a real prototype and a sound experiment design.

Product Engineer, Growth
Growth engineering lives at the intersection of interface changes and measurable lift; here you pre-register metrics, power a controlled experiment, and turn segmented results into a single ship decision the way a growth team must defend every launch.

Interaction Designer, Streaming Media
Streaming products win or lose on the home screen; this challenge builds the exact craft of designing intent-driven layouts and smooth, flicker-free transitions that an interaction designer ships and validates against viewer behavior.
