# 🚀 Day 25/30 – MERN Stack Interview Preparation | JavaScript, React & Backend Interview Practice

Welcome to **Day 25** of my **30-Day MERN Stack Interview Preparation Challenge**! 🎯

In today's interview practice, I answered technical and HR questions covering important MERN Stack concepts such as:

✅ Tell Me About Yourself
✅ Prototype & Prototype Chain

✅ Controlled vs Uncontrolled Components
