Ever Wondered How HackerRank Challenges are Built?

Ever Wondered How HackerRank Challenges are Built?

We’ve built an expert network of 500+ developers from around the world. Through this network, we carefully curate real-world challenges that mirror a developer’s day-to-day job.

Unlike typical leet-code–style problems, our challenges go further. Developers work on code repositories where they need to fix bugs, enhance features, improve performance, and review code—just like they would in real projects.

These challenges are trusted by millions of developers to learn, upskill, and get hired. 

How It Works

  • You will participate in this contest featuring real-world coding scenarios.

  • Eligible top performers will get an invite to join the network.

  • Once you join the network, you will be part of a paid program—you’ll be rewarded for your contributions to build the world’s best developer challenges.

This is your opportunity to build JavaScript challenges

designed for the real-world.
