# 🚀 DevCalc Interview Questions — Free Technical Interview Practice (No Signup) Hi Product Hunt! 👋 I'm Aditya, an independent developer, and today I'm launching a feature I wish existed when I was preparing for placements. Whenever I finished studying JavaScript, React, SQL, or Node.js, I wanted a simple way to test my knowledge. Most platforms required: * ❌ Creating an account * ❌ Buying a subscription * ❌ Completing only a few free questions * ❌ Jumping through random questions with no structured learning path So I built **DevCalc Interview Questions**. ### What makes it different? ✅ No signup required ✅ Completely free ✅ Structured learning path ✅ Real interview questions ✅ Detailed explanations for every answer ✅ Progress tracking ✅ Stage unlocking (Beginner → Intermediate → Advanced → MNC) Instead of copying questions from one source, I researched interview experiences, documentation, community discussions, and commonly asked concepts to build a practical interview preparation platform. ### Currently Available * JavaScript * React * TypeScript * Next.js * Node.js * SQL More technologies are being added continuously. 🔗 Try it here: https://www.devcalc.in/interview... I'd genuinely love your feedback. What technology should I add next? Thank you for checking it out! ❤️ #ProductHunt #BuildInPublic #WebDevelopment #JavaScript #React #NextJS #InterviewPreparation #Developers #IndieHackers
