Node.js coding interviews go beyond basic JavaScript—they test your ability to write clean server-side code, reason through async operations, and design scalable, production-ready APIs. This track offers hands-on practice with the types of challenges asked in real-world interviews for backend and full-stack roles using Node.js. You’ll work through questions covering core Node.js runtime behavior, middleware logic, async patterns like callbacks and promises, and practical server-side challenges like building authentication flows, handling requests under load, or managing rate limits. Each problem includes structured hints, clean solutions, and step-by-step walkthroughs using JavaScript in a Node.js environment. Whether you're interviewing at a startup or a large tech company, this track helps you prepare for interviews that expect real backend fluency, not just frontend experience.
