AI Overlay for Greenhouse Coding Assessments on Mac

· 3 min read
Greenhouse · CoderPad and HackerRank integrations

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.

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.
