💬 Potential Interview Questions

Can you describe your experience developing in React for large-scale web applications?
Developed and maintained component-based UIs using React, focusing on reusability, performance, and integration with RESTful APIs and state management tools.
How do you apply HTML5 and CSS best practices in responsive web design?
Use semantic HTML5 elements, Flexbox/Grid for layout, media queries for responsiveness, and modular CSS or CSS-in-JS solutions for maintainability.
What are the advantages of using Next.js over traditional React setups?
Offers server-side rendering, API routes, built-in routing, image optimization, and better performance and SEO compared to client-side-only React.
How do you ensure accessibility in your React applications?
Use semantic HTML, keyboard navigability, ARIA attributes where necessary, and tools like axe-core and Lighthouse to audit accessibility compliance.
Have you worked with email template development? What considerations are important?
Yes—inline styles, table-based layouts, limited CSS support, cross-client testing (Outlook, Gmail), and media queries for mobile optimization are key.
Describe your process when collaborating with stakeholders to gather and refine requirements.
Conduct meetings to clarify needs, translate business language into technical tasks, create prototypes or wireframes for validation, and iterate based on feedback.
What strategies do you use to troubleshoot and resolve UI-related issues?
Use browser dev tools for inspection, isolate components, write regression tests, and apply logging or error boundary components in React.
How do you manage version control and code collaboration in teams?
Use Git with feature branches, consistent commit conventions, pull requests for review, and integrate with CI/CD for automated testing and deployments.
What tools or methods do you use to maintain performance in front-end code?
Code splitting, lazy loading, image compression, minimizing re-renders using React.memo/useMemo, and auditing with Lighthouse.
How do you approach UI/UX design when building new web components or interfaces?
Start with wireframes/mockups, adhere to design systems, ensure accessibility and responsiveness, gather user feedback, and iterate based on usability testing.
