Sample Answer

On my last team, we decided to migrate a core reporting feature from a legacy JSP app to a React + TypeScript frontend, and I was asked to lead it despite having only light React experience. We had six weeks to ship because finance used these reports for month-end close. I gave myself three days of focused ramp-up: official React docs, a small spike building the core table component, and pairing with our one React-heavy engineer. I wrote a short “front-end playbook” covering our patterns: functional components, hooks, folder structure, and testing approach. To move fast without trashing quality, I set up strict TypeScript settings, ESLint + Prettier, and Jest + React Testing Library from day one. We enforced code reviews with at least one experienced reviewer. We shipped on time, cut report load time by ~45%, and kept bug reports to under 1% of monthly active users in the first two months.
