AI Overlay for Greenhouse Coding Assessments on Mac
Greenhouse is the ATS used by most modern tech employers; the actual coding assessment is delivered by a partner pad such as CoderPad, HackerRank, or CoderPad Screen (formerly CodinGame). Greenhouse Interview Kit just stores the partner link and the resulting score.
A Greenhouse coding stage looks like this from the candidate side: an email arrives with a link, you open the link in your browser, and you land in a CoderPad take-home, a CoderPad Live room, a CoderPad Screen multi-question assessment, or a HackerRank test. Greenhouse itself adds the recruiter-side wiring: which assessment, which interview kit, which scorecard, which timing. None of this involves Greenhouse software running on your Mac.
Key points
- Greenhouse is an ATS, not a proctoring vendor; it neither captures nor renders the assessment surface itself.
- CoderPad take-home and CoderPad Live integrate by URL: the pad does the recording, Greenhouse stores the link.
- HackerRank Assessment integration sends a test link from Greenhouse and pulls back a score; HackerRank ProctorAI flags apply only inside HackerRank tab.
- CoderPad Screen (ex-CodinGame) multi-question assessments use the same in-pad event log as CoderPad Live.
- Recruiter-side Interview Kits show notes, scorecards, and links, never your live or recorded screen pixels.

Common questions
Does Greenhouse itself run a proctor on my machine?
No. Greenhouse is the ATS layer; the assessment is hosted entirely by the integrated partner.
Which pad will I actually take?
It depends on the employer configuration. Look at the assessment email URL.
Will HackerRank ProctorAI catch the overlay?
No. ProctorAI watches webcam, microphone, and tab focus inside the HackerRank tab.
Can the interviewer in the Greenhouse Interview Kit replay my screen?
They can replay the in-pad keystroke timeline if the assessment was a CoderPad pad.
