CoderPad is a San Francisco-based technical interview and assessment platform that lets engineering teams evaluate developers in a real, runnable coding environment instead of on a whiteboard. Founded in 2013 by ex-Google and Amazon engineer Vincent Woo, it pairs live collaborative interviews with asynchronous take-home screens across 40+ programming languages, and has hosted millions of technical interviews for thousands of companies. In 2021 it acquired CodinGame to add candidate assessments and a developer skill-building community.

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.
