1. Master Coding Interview Patterns

Grokking the Coding Interview: Patterns for Coding Questions is a foundational course that teaches you how to solve coding problems methodically rather than relying on brute-force memorization. By internalizing these patterns, you’ll be equipped to handle new, unseen problems with confidence.

Highlights:

A curated set of frequently tested coding patterns—like Sliding Window, Two Pointers, and Topological Sort.
Detailed explanations coupled with practical examples.
Focused on helping you quickly identify the best approach for any given problem.

2. Solidify Your Foundations in Data Structures & Algorithms

Grokking Data Structures & Algorithms for Coding Interviews dives deep into the core concepts of computer science that every engineer must master. You’ll learn how to optimize solutions and implement standard algorithms from scratch.

Highlights:

Comprehensive coverage of essential data structures: Arrays, Linked Lists, Stacks, Queues, Heaps, Trees, Graphs, and more.
Classic algorithms explained with step-by-step visualizations.
Problem sets crafted to improve speed, accuracy, and complexity management.

3. Specialized Skill-Building for Advanced Patterns

Once you’ve nailed the basics, you can level up your skills with more specialized courses. For example:

Grokking Advanced Coding Patterns for Interviews: Ideal for senior roles or competitive interviews that demand a deeper understanding of sophisticated problem-solving techniques.
Grokking Graph Algorithms for Coding Interviews: Graph problems are notoriously common in interviews at companies like Google or Meta. This course focuses on BFS, DFS, shortest path algorithms, and more.
Grokking Tree Coding Patterns for Interviews: Trees are a frequent coding interview topic, and this course shows you how to efficiently handle binary trees, binary search trees, and more complex structures.
Grokking the Art of Recursion for Coding Interviews: Many coding challenges can be elegantly solved using recursion. Mastering recursion will help you tackle a range of algorithmic puzzles with ease.
