Grokking the Coding Interview Patterns
Grokking the Coding Interview Patterns is Educative’s flagship course designed to streamline technical interview preparation through pattern recognition. This 55-hour programme teaches 28 fundamental coding patterns that unlock solutions to thousands of LeetCode problems, eliminating the need for random problem-solving practice. Developed by engineers from major technology companies, the course focuses on teaching repeatable approaches to algorithmic challenges commonly found in FAANG interviews. The interactive browser-based format requires no setup, allowing immediate engagement with coding exercises. Students learn to identify problem types quickly and apply proven solution frameworks, significantly improving interview performance. The course emphasises understanding underlying patterns rather than memorising individual solutions, providing a systematic approach to conquering technical interviews at leading technology companies.

What This Coding Interview Preparation Course Covers
The course covers 28 essential coding interview patterns including Two Pointers, Sliding Window, Merge Intervals, Cyclic Sort, Tree Breadth First Search, Tree Depth First Search, and Dynamic Programming variations. Students master specific techniques for handling arrays, linked lists, binary trees, graphs, and heap problems. Each coding interview pattern includes multiple problem variations, teaching recognition techniques and solution frameworks. Advanced topics cover backtracking, topological sort, and bitwise XOR patterns commonly tested at major technology companies.
Educative’s interactive platform delivers hands-on coding practice directly in the browser without requiring development environment setup. Each coding interview pattern begins with conceptual explanations followed by guided problem-solving exercises. Students work through progressively challenging examples, building pattern recognition skills through repetitive application. The course includes detailed algorithmic analysis, Big O complexity discussions, and optimisation techniques. Interactive visualisations help students understand data structure manipulations and algorithm execution flows.
The curriculum directly addresses interview formats used by Google, Amazon, Facebook, Apple, Netflix, and Microsoft. Students develop skills essential for technical screening rounds and on-site algorithmic challenges in competitive technology roles. The curriculum draws on principles of technical interview, applied to real-world scenarios.
