InterviewWatch is a consent-first integrity platform for live remote interviews. A lightweight application monitors machine-level signals to identify potential AI assistance, desktop and web AI tools, hidden cheat overlays, remote-control software, suspicious typing patterns, virtual devices, and unusual display or clipboard activity. It never records the candidate's screen, audio, or video and does not capture typed or clipboard content. Signals appear in a real-time recruiter dashboard and are converted into an explainable integrity score and tamper-evident report for human review, helping employers verify that candidates are genuine and completing interviews independently without invasive surveillance.

Questions & Answers

As answered by people managing Project Euler and InterviewWatch.

Which are the primary technologies used for building your product?

InterviewWatch's answer:

  • Rust
  • C#
  • PSQL

What makes your product unique?

InterviewWatch's answer:

InterviewWatch is a privacy-first interview integrity platform that verifies remote interviews using machine-level signals instead of recording audio or video, tracking eye movements, or analyzing candidate behavior with machine learning. It provides objective, tamper-evident evidence of interview integrity while respecting candidate privacy, helping hiring teams make more confident hiring decisions.

Why should a person choose your product over its competitors?

InterviewWatch's answer:

Unlike traditional interview monitoring/proctoring tools, InterviewWatch does not record audio or video, use eye-tracking, gaze detection, or machine learning to analyze candidate behavior. Instead, it relies on objective machine-level integrity signals to identify risks, providing privacy-friendly, evidence-backed verification with minimal impact on the interview experience.

How would you describe the primary audience of your product?

InterviewWatch's answer:

InterviewWatch is built for companies that conduct remote hiring, including talent acquisition teams, recruiters, hiring managers, staffing firms, and enterprises that want to verify interview integrity and reduce hiring fraud during remote interviews.

What's the story behind your product?

InterviewWatch's answer:

InterviewWatch was born from my experience serving on interview panels. Over time, I interviewed many candidates whose interview performance didn't match their actual understanding. Some struggled to explain the code they had just written or reason through their own solutions. As AI became capable of solving interview problems in real time, it became even harder to know whether an interview reflected a candidate's true abilities. I built InterviewWatch to help companies restore trust in remote hiring through objective, privacy-first interview integrity verification based on machine-level signal, not audio recording, video recording, or behavioral analysis.

Who are some of the biggest customers of your product?

    I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 8 months ago
  • Does hobby programming indicate that you would rather invent than discover?
    I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
