Skills required for Frontend Developer in India (2026)

Frontend Developer roles in India in 2026 require deep JavaScript and TypeScript, React 19 — including server components and concurrent features — and modern state/data patterns (TanStack Query for server state, Zustand or Redux Toolkit for client state). Core Web Vitals literacy is now an explicit JD line: INP, LCP, and bundle discipline get tested, as do accessibility (WCAG 2.2) and responsive CSS without a framework crutch. Next.js experience is requested in most product-company postings, and interviews lean on machine-coding rounds: build a typeahead, an infinite list, or a feature-complete widget in 60–90 minutes.

Must-have skills for a Frontend Developer

The skills Indian employers screen for in 2026, and why each one is asked.

SkillWhy it matters
JavaScript internals (event loop, closures, prototypes, promises)Indian frontend interviews are famous for JS-internals rounds — frameworks change, these questions never do.
TypeScript 5 (generics, narrowing, utility types)Default in every serious codebase; typing a component's props correctly is a live-coding staple.
React 19: hooks, server components, suspense, transitionsMost-demanded framework; interviews probe re-render behaviour and effect-dependency bugs.
CSS at production depth (flexbox, grid, container queries, layers)Machine-coding rounds require pixel-accurate layout without a UI library.
State management patterns (TanStack Query, Zustand/Redux Toolkit)Distinguishing server state from client state is a 2026 interview shibboleth.
Performance: Core Web Vitals (INP, LCP, CLS), code-splittingE-commerce and fintech employers tie Web Vitals to revenue and test optimisation methodology.
Accessibility (semantic HTML, ARIA, keyboard navigation)WCAG compliance is contractual for GCCs serving US/EU clients; a11y questions are screening filters.
Next.js rendering strategies (SSR, SSG, ISR, streaming)The default production framework; choosing a rendering mode per page is a design-round question.
Testing (Vitest/Jest, React Testing Library, Playwright)Component tests are expected in take-homes at product companies.
Browser fundamentals (critical rendering path, caching, CORS)Debugging rounds present a slow or broken page and watch your methodology.

Certifications that help

Typical interview topics

  1. Machine coding: typeahead with debounce, caching, and keyboard navigation
  2. Why does this component re-render? Fix it without memo-spam
  3. Implement infinite scroll with IntersectionObserver
  4. Optimise a page from LCP 4.5s to under 2.5s — full methodology
  5. Closures and the classic setTimeout-in-a-loop question
  6. Promise.all vs allSettled vs race — implement one from scratch
  7. Design a reusable modal: focus trap, portal, a11y
  8. CSS: centre/overlap layouts live, container queries vs media queries
