HackerRank was founded in 2012 by Vivek Ravisankar and Hari Karunanidhi, who saw an opportunity to fix technical hiring. The platform serves two audiences: companies that need to evaluate developers’ coding skills, and programmers who want to practice and prove their abilities through challenges.
For developers, HackerRank offers thousands of practice problems across domains like algorithms, data structures, mathematics, SQL, AI, and language-specific challenges. Problems are organized into tracks and difficulty levels, and the platform supports over 35 programming languages. Completing challenges earns badges and points that contribute to a public developer profile.
The business side of HackerRank is where the real revenue comes from. Companies use the platform to create custom coding assessments for job candidates, run hackathons, and conduct technical interviews with a shared code editor. Over 3,000 companies — including Goldman Sachs, Airbnb, and Bloomberg — use HackerRank for their hiring pipelines. The platform’s automated assessment tools save engineering teams hours of manual screening.
HackerRank has also built a competitive programming community with regular contests and a global leaderboard. The platform’s “HackerRank for Work” product handles everything from initial screening to live technical interviews. With millions of developers on the platform and strong adoption among employers, HackerRank sits at the intersection of education and hiring in a way few competitors can match.
