Episode 1 : The Leetcode Lie

Solving 500 random Leetcode problems is the fastest way to fail your technical screen. Here is the pattern framework you actually need. 👇

Top-tier tech companies don’t ask verbatim questions. They disguise standard algorithmic patterns inside thick, real-world constraints. If you are just memorizing solutions, you will freeze the second an interviewer tweaks a variable.
Stop doing random “Mediums.” Group your study sessions by these 4 high-ROI patterns:

1️⃣ The Sliding Window
• When to use: The prompt asks for a “maximum / longest / shortest” contiguous subarray or substring.
• The Goal: Turns an O(n²) brute-force nested loop into a clean O(n) pass.

2️⃣ Two Pointers
• When to use: You are dealing with sorted arrays or linked lists and need to find pairs, merge elements, or detect cycles.
• The Goal: Constant space complexity O(1) optimization.

3️⃣ BFS / DFS on Matrices
• When to use: The problem involves a grid, shortest path, “number of islands,” or network connectivity.
• The Goal: If you can’t traverse a 2D grid in your sleep, you aren’t passing the technical screen.

4️⃣ Topological Sort
• When to use: The prompt involves scheduling, prerequisites, or dependency resolution (e.g., building a build-system or course schedule).
• The Goal: This is the pattern that instantly separates mid-level candidates from the rest of the pack.
