Study Placement - Invidious

Study Placement

Hi, I'm Ashish, Software Engineer at MongoDB. I created Study Placement to help students crack top tech companies through strong problem-solving skills and structured preparation.

On this channel, you'll find:

🚀 Step-by-step LeetCode solutions
📚 Beginner to advanced DSA lectures
💻 Coding interview preparation
🎯 Online Assessment (OA) strategies
🏢 Real interview experiences from companies like Amazon, Google, Microsoft, TCS, Infosys, and startups
🧠 Logic-building techniques and optimal coding approaches

I believe that understanding the logic is more important than memorizing solutions. Every problem is explained with intuition, dry runs, and clean code so that you can solve similar questions on your own.

Whether you're a beginner or preparing for placements, this channel is designed to make your journey easier and more effective.

🎯 Subscribe and let's crack coding interviews together!
