💬 Potential Interview Questions
-
How do you approach building and maintaining high-impact customer-facing pages like catalog and delivery flows?
I focus on clear information hierarchy, fast loading times, and predictable interactions, while keeping the code modular so features can evolve without breaking critical user journeys. -
How have you improved Core Web Vitals in a production frontend application?
I’ve improved CWV by optimizing bundle size, reducing JavaScript execution, using lazy loading, improving server-side rendering, and carefully managing images and fonts. -
What are your best practices when working with Vue and TypeScript at scale?
I rely on strong typing for APIs and state, composable functions for shared logic, consistent patterns for components, and clear boundaries between domain and UI concerns. -
How do you ensure accessibility in complex e-commerce flows?
I use semantic HTML, keyboard-friendly interactions, proper ARIA attributes when needed, and regularly test with screen readers and automated a11y tools. -
How do you balance SEO requirements with rich, interactive frontend experiences?
I ensure critical content is server-rendered or statically generated, avoid blocking scripts, use semantic markup, and enhance pages progressively with interactivity. -
Describe your approach to modernizing legacy frontend code.
I refactor incrementally, add tests around critical paths, replace outdated patterns with modern abstractions, and avoid large rewrites unless absolutely necessary. -
How do you collaborate with backend teams on API contracts and performance?
I align early on data needs, define clear contracts, push for backend support of frontend performance (batching, caching), and continuously validate assumptions with real usage data. -
How do you design and evolve a component library or design system?
I focus on reusable, well-documented components with clear APIs, accessibility built in by default, and close collaboration with designers to ensure consistency. -
How do you use AI tools like ChatGPT or Cursor in your daily frontend work?
I use them to speed up boilerplate, explore solutions, review code, and validate ideas, while always applying engineering judgment and reviewing outputs critically. -
How do you mentor other frontend engineers in a senior role?
I mentor through code reviews, pairing, architectural discussions, and by setting clear standards, helping others grow ownership and confidence in their decisions.
