Frequently Asked Interview Questions (With Answers & Solution Guidelines)
Next.js Rendering Strategies
- Question:“How do you decide between Server-Side Rendering (SSR), Static Site Generation (SSG), and Client-Side Rendering (CSR) in Next.js for enterprise dashboards?”
- Answer & Solution Context: Detail that SSG is ideal for static, SEO-focused content built at compile time. SSR is best for dynamic pages requiring real-time user-specific data per request (e.g., authenticated user dashboards). CSR is reserved for highly interactive, non-SEO UI components that fetch data client-side after initial shell rendering.
Full-Stack Performance & PostgreSQL Optimization
- Question:“What steps do you take to identify and optimize a slow API endpoint powered by Flask and PostgreSQL?”
- Answer & Solution Context: Explain profiling the Flask endpoint to isolate network vs. execution overhead. For database bottlenecks, analyze query execution plans using
EXPLAIN ANALYZEin PostgreSQL, add missing indexes, refactor complex queries into materialized views where appropriate, and implement connection pooling or redis caching for frequently accessed static payloads.
