CoderPad

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.
