# 🚀 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.

What technology should I add next?
Thank you for checking it out! ❤️
