DSA Patterns: The Complete Interview Sheet with Aman Saxena

DSA Pattern-Wise Interview Sheet — Made by Me, For Your Interview Success

I personally curated this sheet after spending countless hours studying DSA patterns. I have strong knowledge of these patterns from solving and teaching them, and I built this to save you the confusion I went through.

Most people solve hundreds of random LeetCode problems and still freeze in interviews — because they memorized solutions instead of learning patterns. This sheet fixes that.

What's inside:

📚 Pattern-wise questions for every topic — Arrays, Two Pointers, Sliding Window, Binary Search, Linked List, Stacks, Heaps, Backtracking, Trees, Graphs, DP, and Strings.

🔑 Keywords to focus on — For every pattern, I've listed the exact words that show up in questions, so you instantly know which pattern to use.

🧠 Easy tricks to remember each pattern — So you don't forget the approach under pressure.

📋 Cheat Sheet — Quick table mapping question signals to patterns, great for last-minute revision.

❓ Quiz at the end — Test yourself on real problems before checking the answer, to build actual recognition skill.

📅 7-Day Revision Plan — With tracks for 30 min, 60 min, or 2-3 hours a day.

✅ Progress Tracker — See which patterns you've learned, solved, and revised.

⏱️ Last 30-Minutes Checklist — A short, high-value list for right before your interview.

Built on one simple idea: Recognize → Select → Apply → Variate. Stop memorizing, start understanding.
