Study Placement
Welcome to Study Placement!
This channel is for students and freshers preparing for tech placements. We cover step-by-step solutions to LeetCode problems, clear and beginner-friendly DSA lectures, and tips for cracking online assessments and interviews.
From arrays and recursion to graphs and dynamic programming — everything is explained in simple language with proper logic and code walkthroughs.
We also share real questions asked in companies like Amazon, Infosys, TCS, and startups, along with mock interviews and placement strategies.
Whether you’re in college or doing self-preparation, this channel will help you build confidence and get placement-ready.
