Title: How I Cracked My Coding Interviews with a Simple Pattern-Based DSA Approach

(and How You Can Too)

...

You’ve probably seen this before:
You open a DSA question, stare at it for 20 minutes, and then… Google the solution.

...

The problem?
You’re learning problems, not patterns.

...

When I was preparing for my interviews, I realized something game-changing:
Almost every coding problem falls under a repeatable pattern.

...

Instead of trying to “learn everything,” I focused on:

  • Mastering Time Complexity Basics
  • Cracking problems with Kadane’s Algorithm
  • Moving up to Two Pointers, Sliding Window, Binary Search on Answer
  • Then tackling Graphs, Tries, and Competitive Programming problems.

...

Why Patterns Work Better Than Random Practice

  • You solve faster because you’ve seen the core idea before.
  • You can adapt the pattern to multiple variations.
  • You feel confident in interviews — even with new problems.

...

What I’ve Created for You

I’ve put together my personal DSA Pattern Notes + 150 Interview Problems in a clean, structured format on Notion.

This includes:

  • Step-by-step explanations
  • Time & space complexity analysis
  • Example problems from LeetCode, Codeforces, and InterviewBit
  • My CP-ready templates in JavaScript, Java, and C++

...

How to Get It

I’m making it available for a small one-time payment — because good preparation saves months of job hunting.
You’ll get lifetime access + updates whenever I add new problems.
