IntermediateLEADERSHIP
Tell me about a time you led the front-end direction of a feature or project (e.g., choosing framework, architecture, or tooling). How did you align the team, handle disagreements, and ensure the solution was maintainable over time?

Sample Answer

On my last team, I led the front-end direction for a new analytics suite that was expected to serve ~200 internal users daily. We had a legacy jQuery/Backbone app and a split opinion on whether to move to React or stick with what we had. I proposed a modular React + TypeScript architecture with a design system, but limited the blast radius by starting with a single vertical slice. To align everyone, I ran a spike with two prototypes: one in the legacy stack, one in React, and measured dev time, bundle size, and complexity. The React version cut implementation time by ~35% and reduced duplicate UI code by about 40%. That data helped resolve most disagreements. We standardized on a monorepo with shared UI components, Storybook for documentation, and strict ESLint/Prettier rules. Six months in, we’d shipped 5 new dashboards, and onboarding new engineers dropped from ~3 weeks to about 1 week because the patterns and tooling were so consistent.
