LeetCode is the #1 platform for coding interview preparation. From Amazon to Google, nearly every tech company pulls its questions from LeetCode-style patterns. But solving 500+ problems blindly isn’t the smartest way.
With structured PDFs and targeted practice sheets, you can master patterns, track your progress, and ace interviews faster.
Why LeetCode is the Gold Standard for Interview Prep
LeetCode helps you:
- Solve real DSA problems asked by top tech firms.
- Build consistency with daily streaks and contests.
- Master topics like sliding window, binary search, graphs, dynamic programming, and recursion.
- Practice in Python, Java, C++, or JavaScript with instant feedback.
If you're serious about cracking FAANG or Tier-1 roles, LeetCode is non-negotiable.

FAQs on LeetCode & Free Preparation PDFs
Q1. How many LeetCode problems should I solve to get a job?
Around 150–200 strategically chosen problems across 12 topics is sufficient if you master them deeply.Q2. Can I crack FAANG using only LeetCode?
Yes, if you combine DSA mastery with system design and mock interviews, LeetCode alone covers coding rounds well.Q3. Is this method suitable for non-CS students?
Absolutely. The PDFs break down topics in a step-by-step roadmap, perfect for non-technical backgrounds too.Q4. How is LeetCode better than GFG or Codeforces?
LeetCode focuses on interview-type questions, whereas Codeforces leans competitive and GFG is more theoretical.
