he Visual Guide to 15 Essential Coding Interview Patterns

You don’t need to memorize 500 solutions. You need to recognize the patterns underneath them.

This visual guide focuses on 15 recurring problem-solving patterns that appear throughout coding interviews, including Sliding Window, Two Pointers, Binary Search, DFS/BFS, Backtracking, Dynamic Programming, Heaps, Tries, Greedy algorithms, and more.

Each pattern is introduced visually before the code, helping you recognize the signals that indicate which technique to use.

You’ll work through examples in Python and Java, with practice problems designed to turn pattern recognition into an instinct you can apply to unfamiliar questions.
