What a strong Frontend Engineer CV must show
Framework depth (React, Vue or Angular)
Not just framework familiarity, but demonstrated mastery of lifecycle hooks, state management (Redux, Vuex, NgRx), and component composition patterns. Look for candidates who've shipped real products, not tutorial projects. Klearskill check: Scans CV content and GitHub links for specific framework terminology (useReducer, higher-order components, props drilling solutions, context API), years shipped in production, and complexity of state management challenges solved.
CSS and styling expertise
Deep CSS knowledge separates senior frontend engineers from juniors. This includes flexbox/grid mastery, CSS-in-JS frameworks, responsive design implementation, and understanding of cascading and specificity. Avoid candidates who list CSS as a checkbox skill. Klearskill check: Detects CSS depth signals: mentions of CSS Grid, Flexbox, SCSS/LESS, CSS modules, styled-components, Tailwind CSS expertise at scale, and evidence of responsive design across multiple screen sizes. Flags pure CSS-in-JS dependency without core CSS fundamentals.
Web accessibility (WCAG, semantic HTML)
Accessibility-first thinking is rare but essential. Candidates should understand ARIA roles, semantic HTML, keyboard navigation, and WCAG 2.1 compliance. This signals they've built for real users, not just happy paths. Klearskill check: Searches for WCAG, ARIA, accessibility audits, screen reader testing, keyboard navigation work, or axe-core/Lighthouse accessibility improvements. Also identifies candidates who've worked on inclusive design or accessibility-focused projects.
Performance optimisation experience
Real frontend engineers obsess over metrics: LCP (Largest Contentful Paint), CLS (Cumulative Layout Shift), bundle size reduction, image optimisation, and lazy loading. Look for candidates who've measurably improved Core Web Vitals. Klearskill check: Identifies performance-focused keywords: Lighthouse scores, Core Web Vitals improvements, bundle size reduction, code splitting, lazy loading implementation, image optimisation, and evidence of performance monitoring (New Relic, Datadog).
Testing discipline (unit, integration, E2E)
Candidates should demonstrate testing competency: unit tests with Jest, integration tests, and E2E tests with Cypress or Playwright. Watch for test coverage percentages and testing pyramid understanding. Klearskill check: Detects testing signals: Jest, Vitest, React Testing Library, Cypress, Playwright, Testing Library mentions. Flags candidates with test coverage percentages, testing discipline language, and mention of testing trade-offs or testing strategies.
Version control and Git workflow
Proficiency with Git is baseline. Look for evidence of feature branching, rebase vs merge understanding, commit message discipline, and collaborative workflows. This reflects code quality culture. Klearskill check: Searches for Git mentions, GitHub profiles linked, GitFlow/trunk-based development mentions, pull request discipline language, and evidence of code review participation.
REST API and GraphQL consumption
Frontend engineers must understand API design patterns, pagination, caching strategies, and error handling. GraphQL experience (Apollo, Relay) is a strong signal for senior engineers who think beyond REST. Klearskill check: Identifies API integration signals: REST, GraphQL, Apollo Client, Relay, fetch/axios usage, API error handling, caching strategies (React Query, SWR), and experience with API rate limiting or pagination challenges.
Signals that set candidates apart
TypeScript expertise
Strong typing prevents runtime errors and improves code clarity. Candidates comfortable with TypeScript generics, interfaces, and type-safe patterns are significantly more productive.
Design system work
Experience building or contributing to component libraries, design systems, or UI kits shows systematic thinking and scalability mindset.
Build tool expertise
Webpack, Vite, Parcel, or Rollup experience indicates understanding of module bundling, asset optimisation, and development workflow optimisation.
Internationalisation (i18n) experience
I18n work (react-i18next, Intl API) demonstrates user empathy and technical depth beyond English-centric development.
Monitoring and observability
Experience with error tracking (Sentry), analytics, or performance monitoring tools shows production mindset and debugging discipline.
What Klearskill flags to watch for
Framework-hopping without substance
CVs listing React, Vue, Angular, and Svelte with equal experience claims suggest checkbox learning rather than deep expertise. Watch for candidates who've spent 3 months on each framework.
No mention of testing or QA
Frontend engineers who never mention testing, unit tests, or test coverage are likely to ship breaking changes. This is a strong red flag for code quality.
CSS gaps masked by CSS-in-JS dependency
Candidates who exclusively use Tailwind or styled-components without demonstrating core CSS knowledge (Grid, Flexbox, cascading) may struggle with custom styling challenges.
Accessibility never mentioned
Complete absence of WCAG, ARIA, keyboard navigation, or accessibility mentions suggests candidates haven't built for inclusive design or real-world constraints.
Portfolio or GitHub links are empty or outdated
Strong frontend engineers have public work samples. Missing or dormant repos suggest either portfolio anxiety or disengagement from craft.
Only freelance or bootcamp projects listed
Without evidence of production systems, team collaboration, or handling scale, candidates may struggle with code reviews, testing discipline, and shipping velocity.

Frontend Engineer screening questions
How does Klearskill identify React vs Vue vs Angular expertise?
Klearskill's AI reads CV content and linked GitHub repositories, detecting framework-specific signals: React hooks patterns, lifecycle methods, context API usage, component composition patterns, and ecosystem tooling (Redux, Next.js). For Vue, it recognises composition API, Vuex patterns, and Vue-specific project structure. For Angular, it identifies service injection, RxJS observable patterns, and decorator usage. The AI also measures production experience depth by analysing project complexity and team size, separating framework tourists from engineers who've shipped at scale.
Can your AI detect CSS depth vs CSS-in-JS surface-level usage?
Yes. Klearskill distinguishes genuine CSS expertise from framework-dependent styling by scanning for core CSS knowledge: CSS Grid and Flexbox mastery, SCSS/LESS preprocessing experience, responsive design implementations, and CSS architecture patterns. Candidates relying solely on Tailwind without demonstrating CSS fundamentals get flagged. The AI also checks for accessibility-focused styling decisions (colour contrast, focus states) and performance-aware CSS practices, indicating engineers who understand styling systems beyond utility class selection.
How do you assess accessibility awareness from CVs?
Klearskill searches for accessibility-specific language: WCAG compliance mentions, ARIA implementation, semantic HTML emphasis, keyboard navigation experience, and screen reader testing. It also identifies candidates who've worked on accessibility audits, used tools like axe-core or Lighthouse, or contributed to accessible component libraries. These signals indicate candidates who've genuinely built inclusive experiences, not those who treated accessibility as checkbox compliance. Complete absence of accessibility mentions is flagged as a concern for teams prioritising inclusive design.
What makes screening frontend engineers different from other roles?
Frontend engineering screening is harder because CVs don't reveal CSS depth, design system thinking, or accessibility awareness effectively. A CV might claim React mastery but hide outdated patterns or lack of testing discipline. Klearskill screens specifically for production-scale frontend work: performance optimisation metrics, component architecture decisions, testing pyramid discipline, and accessibility-first thinking. Our AI also validates GitHub links and portfolio evidence, separating candidates with real shipping experience from those with impressive-looking CVs but shallow technical foundations.
