What this interview will probe
Work on the Next.js open-source framework that powers a large share of the React ecosystem, building features across the App Router, React Server Components, and the Rust-based Turbopack bundler and compiler. You would balance developer ergonomics with build performance while shepherding changes through a heavily-used public repo and large community. A technical interview would probe deep understanding of React rendering and hydration internals, bundler/compiler design tradeoffs, and how to evolve a framework API without breaking millions of downstream apps.
