AI Overlay for CodeSignal General Coding Assessment on Mac
CodeSignal is the assessment behind the General Coding Assessment (GCA) that companies like Robinhood, Capital One, and Brex use to triage early-career engineering candidates. Most CodeSignal sessions are async, proctored by webcam and a human review team rather than a live interviewer.
CodeSignal was founded in 2014-2015 by Tigran Sloyan, Aram Shatakhtsyan, and Felix Desroches, originally as CodeFights and rebranded in 2018. The flagship product is the General Coding Assessment, a 70-minute four-question test that produces a Coding Score from 300 to 850 used for hiring triage. Proctoring is layered: ID verification at session start, webcam recording throughout, microphone monitoring, screen-share via getDisplayMedia, plus a Suspicion Score computed from behavioral signals.
Reviewers are looking for second screens, second people, paste events, and tab-switch patterns. The overlay creates none of these signals on the recording.
CodeSignal does cross-candidate plagiarism checks and looks for code that matches known model output patterns.
CodeSignal flags multiple displays via the screen-share consent dialog. Use only your built-in display.
CodeSignal pauses the session and lets you resume. The overlay is local to your Mac.
Yes, practice mode is unproctored and unscored for the employer.
