Vivek Ravisankar
Vivek Ravisankar is the co-founder and CEO of HackerRank, the technical hiring platform he started in 2012 after leaving a developer job at Amazon. Frustrated by the hours engineers lost to unstructured interviews, he and co-founder Hari Karunanidhi built a way to measure programming skill directly. After several pivots and three tries at Y Combinator, HackerRank grew into a platform used by thousands of companies and millions of developers. Ravisankar's stated mission is to build a meritocracy in hiring, where a developer's skills matter more than their school, geography, or resume brands.
HackerRank
HackerRank is a technical skills platform that helps companies screen, interview, and hire developers based on what they can actually build rather than what their resume claims. Founded in 2009 by Vivek Ravisankar and Hari Karunanidhi, the company runs a two-sided model: a community where millions of developers practice coding challenges, and an enterprise product that lets 3,000+ companies - including a large share of the Fortune 100 - assess candidates with real-world coding tests, live pair-programming interviews, and, increasingly, AI-assisted evaluation and proctoring.
