Technical Interview Questions & Model Answers
Q1What is the main architectural benefit of React Server Components in Next.js 15?
Answer: React Server Components execute exclusively on the server, significantly reducing client JavaScript bundle size and enabling secure, direct database access without exposing internal credentials.
Q2How does Next.js App Router implement streaming and progressive rendering?
Answer: Next.js utilizes React Suspense boundaries combined with HTTP chunked transfer encoding to deliver instant shell markup while asynchronously streaming resolved data token-by-token.
Q3Why is schema validation with Zod recommended for TypeScript backend handlers?
Answer: Zod parses and validates incoming runtime HTTP payloads against defined schemas, bridging the gap between static TypeScript types and untrusted client inputs to prevent unexpected runtime crashes.
Q4How does the Result pattern improve backend error handling compared to throw statements?
Answer: The Result pattern models success and failure as explicit return values, forcing callers to handle potential errors at compile time and preventing unhandled promise rejections.
Q5What advantages do headless UI primitives like shadcn/ui provide over traditional component libraries?
Answer: Headless primitives offer accessible, unstyled interaction logic with full WAI-ARIA compliance while allowing developers to retain total ownership and customization of CSS classes.
