This guide is for Indian job seekers preparing for Node.js backend roles, from freshers facing their first technical round to experienced developers aiming for senior positions at product companies and service firms. It covers what interviewers ask most in 2025 and 2026 on Node 20 and 22: the event loop and libuv, modules, async patterns, streams and buffers, Express middleware, error handling, clustering and worker threads, security, performance, REST API design and testing. Questions are grouped as easy, medium and hard. Read each answer, run the code yourself, and then explain it aloud in your own words.
