Master DSA patterns asked in every interview

I failed 10 interviews in a row.
Not because I wasn’t smart—
But because I didn’t master the patterns every interviewer expects you to know.

Here are the 5 DSA patterns that changed everything for me:

1️⃣ Sliding Window – For optimizing problems on arrays and strings.
2️⃣ Two Pointers – Simplifies searching and sorting challenges.
3️⃣ Fast & Slow Pointers – Perfect for detecting cycles and linked list problems.
4️⃣ Binary Search – A must-know for efficient searching in sorted data.
5️⃣ Dynamic Programming – The key to cracking tough problems with overlapping subproblems.

Once I understood these deeply, I started solving questions faster, and my confidence skyrocketed.

If you’re struggling in interviews, start here. These are your foundation.
