CodeSignal

CodeSignal is a technical interview and assessment platform operated by American company BrainFights, Inc. It was founded in 2014 and headquartered in San Francisco.

History
CodeSignal, initially called CodeFights, was founded in 2014 by Tigran Sloyan, Aram Shatakhtsyan, and Felix Desroches.

CodeFights provided a platform for developers to compete in head-to-head timed coding challenges. In 2017, CodeFights began to offer an interview practice mode.

In 2018, the company changed the name of its platform from CodeFights to CodeSignal, and introduced a Coding Score that developers could share with technical recruiters, based on assessments completed on CodeSignal.

Platform
The CodeSignal platform consists of Tech Screen, Pre-Screen, and Interview products used by technical recruiters and hiring managers to source and qualify candidates for software engineering positions. Users select from a bank of coding tasks, create custom coding questions, or use a skills assessment framework like the General Coding Assessment (GCA). CodeSignal is a cloud-based software as a service (SaaS) product that integrates with applicant tracking systems (ATS) like Greenhouse and Lever.
