My Hot Take On The Leetcode Obsession

Introduction

LeetCode has become a dominant focus for many developers preparing for technical interviews. While solving algorithmic problems can sharpen certain skills, the current culture around grinding thousands of questions raises concerns about its true value.

The Problem with the LeetCode Obsession

• Efficiency: Modern AI can solve many LeetCode problems in minutes, yet we still spend countless hours on repetitive patterns.
• Retention: Most people do not remember the exact solution to a problem they solved months ago. The practice often turns into memorization rather than genuine understanding.
• Opportunity Cost: Time spent on endless interview puzzles could be directed toward learning operating systems, exploring AI, contributing to open‑source projects, building automations, or scaling real applications—areas that provide deeper, more practical knowledge.

What Matters More Than Solving Hundreds of Problems

Real‑World Skills

• Learning Linux, system internals, and orchestration tools.
• Contributing to open‑source projects and building useful utilities.
• Designing, deploying, and scaling production‑grade applications.

Competitive Programming (When It’s Fun)

Platforms such as Codeforces, CodeChef, and AtCoder offer challenging contests that can be rewarding for those who enjoy competition. However, pursuing them solely because “companies demand it” can lead to burnout.

Learning Data Structures and Algorithms (DSA) vs. Grinding

• Fundamentals are essential: Understanding trees, graphs, recursion, hash maps, and linked lists is valuable and foundational to computer science.
• Depth over breadth: Solving a handful of well‑chosen problems to grasp these concepts is beneficial.
• Diminishing returns: Solving hundreds or thousands of similar problems adds little beyond the initial learning phase and often becomes rote memorization.

The Cultural Issue

The current mindset treats “solving the top 100 interview questions” as the ultimate benchmark of engineering ability. This perception:

1. Elevates puzzle‑solving above real system knowledge.
2. Encourages a checklist mentality rather than curiosity‑driven learning.
3. Turns interview preparation into a badge‑collecting exercise rather than skill development.

Personal Reflection

I spent years following a DSA sheet, solving every problem, taking notes, and revisiting them later. Eventually, I met peers who were building homelabs, customizing Linux setups, and contributing to open source. Their work felt far more engaging than another batch of LeetCode questions. Looking back, I realize that prioritizing real‑world projects would have been a better use of my time.

Takeaway

You have two paths:

1. Follow the conventional route – solve countless interview puzzles and join the crowd of developers who have “checked the box.”
2. Pursue what excites you – focus on building systems, learning new technologies, and having fun along the way.

Choose the path that brings you joy and lasting growth. Have fun.
