LeetCode: The Billion-Dollar Interview Gatekeeper
How a platform for coding practice became the world's most important tech hiring filter
In the last 24 hours, 29.8 million developers logged into LeetCode—not to build products, but to solve algorithmic puzzles that could make or break their careers. This isn't just a learning platform; it's the standardized gatekeeper for the global tech industry.
"LeetCode didn't invent coding challenges—it industrialized them, turning interview prep from a niche activity into a $41.9M/year business model."
The Silent Hiring Filter
With 71% direct traffic (22% organic), LeetCode's dominance is self-reinforcing: companies use it to filter candidates, so candidates practice on it, which makes companies use it more. The 1.35M monthly searches for 'leetcode' alone reveal a captive audience that treats the platform as mandatory infrastructure, not optional education.
The Network Effect Engine
LeetCode's 34.5M backlinks and 56.8% traffic from 'undefined' countries (likely China and India) show its global, language-agnostic reach. Unlike competitors who localize content, LeetCode standardized the language of interviews: English problem statements with universal logic. This creates a single playing field for Bangalore, Beijing, and Berlin.
The platform's tech stack (jQuery, Tailwind, Bootstrap, Ant Design) reveals a pragmatic, not cutting-edge, approach. They're not building a flashy product—they're building a reliable utility. The 2.7/5 Trustpilot rating from just 13 reviews suggests either low user engagement with review platforms or a user base that treats it as a necessary tool, not a beloved product.
- The 'LeetCode 150' is now the unofficial CS curriculum for bootcamps worldwide
- Top keywords ('leetcode sql', 'leetcode login') show users treating it as a daily tool, not a one-time resource
- 272 employees generating $41.9M/year = $154K revenue per employee—efficient but not explosive growth
LeetCode is infrastructure, not education
It doesn't teach you to code—it certifies you're hireable. In a world where coding skills are commoditized, that's a far more valuable (and profitable) position.

Great free tier, worth the premium
Lots of clear problems, good catalogue with filters, great editorial explanations. I use it to prepare for interviews, I don't care about cheaters. Most Explore topics are good, but some are outdated and poorly structured

I'm new to this website and returned to coding after my Masters after 2 or 3 years. I believe this is a very good website to brainstorm your studies mind and give your brain a good push to think.
