Terms of Service

The terms governing use of Eigen-Rho by hiring companies and the candidates they invite to live proctored data interviews.

Last updated: 10 June 2026

These terms set out how Eigen-Rho may be used. They apply to two kinds of people: the hiring companies that run interviews on the platform, and the candidates those companies invite to take part. Please read the sections that apply to you. Words in these terms have the meanings given in the Definitions section below.

1. Acceptance

By using Eigen-Rho, you agree to these terms. A hiring company accepts them when it signs a pilot agreement or otherwise begins using the service. A candidate accepts them when joining an interview. If you do not agree, please do not use the platform. Where a candidate is a minor under the law of their location, a parent or guardian should review these terms on their behalf.

2. Definitions

• Eigen-Rho (also "we", "us", "our") means the company that provides this platform.
• Company (also "you", where the context is a hiring customer) means an organisation that uses Eigen-Rho to interview candidates.
• Interviewer means a person, acting for the Company, who conducts a live interview and makes the hiring judgment.
• Candidate means a person invited by a Company to take part in an interview on the platform.
• Pilot agreement means the separate written agreement between Eigen-Rho and a Company that sets commercial terms, data retention, governing law, and any other specifics. Where the pilot agreement and these terms differ, the pilot agreement controls for that Company.

3. The service

Eigen-Rho is a live, one-to-one, human-proctored data interview. A candidate solves a real business case by writing live SQL against seeded data in the browser, while an interviewer watches over a video call. The platform supports the interviewer with a working environment and a set of integrity signals; it does not replace the interviewer.

SQL written by the candidate runs on our servers in read-only mode, inside an isolated database created for that session. The answer key never reaches the browser. The question can change during the interview (a "twist"). When a query is run, the platform compares the result to a golden answer and produces two separate scores, one for skill and one for integrity. These two scores are never blended into a single number.

4. Acceptable use

Everyone who uses the platform agrees not to:

• copy, scrape, or harvest the case library, questions, seeded data, or other platform content;
• share, publish, or resell answer keys, golden answers, or solutions;
• reverse engineer, decompile, or attempt to extract the source code or underlying models of the platform;
• probe, scan, or test the security of the platform except as permitted in writing by us;
• use the platform to break the law, infringe someone else's rights, or interfere with others' use of the service.

5. Company responsibilities

A Company that uses Eigen-Rho agrees to:

• use the platform only for lawful hiring and assessment, and not for any unlawful or discriminatory purpose;
• give candidates the notices we provide, or equivalent notices, before an interview, so candidates understand how proctoring works as described on our Privacy page;
• obtain any consents that the law of the candidate's location requires, and handle candidate data lawfully once it is in the Company's hands;
• have a qualified interviewer conduct each interview and make the hiring judgment, rather than relying on the platform's signals on their own;
• keep account credentials secure and limit interviewer access to people who need it.

The Company is responsible for its own hiring decisions and for meeting the employment, privacy, and equal-opportunity laws that apply where it hires.

6. Candidate terms

When a candidate joins an interview, they agree to:

• take part in proctoring as described on our Privacy page. In plain terms, this means face-presence detection (analysis runs in the candidate's browser; no identity matching, no face templates stored), and the recording of integrity signals such as tab or focus loss, second-monitor presence, paste events, camera on or off, face presence or absence, and typing rhythm;
• do their own honest, individual work during the interview;
• not seek or use outside help, and not share the case, questions, or solutions afterward.

During the interview, the live camera is relayed to the interviewer only and is never recorded or stored by us. Microphone audio stays on the candidate's device; only a coarse voice-activity flag (quiet or voice) is transmitted. A candidate may decline or stop at any time, though doing so may mean the Company cannot complete the interview. Candidates can find more detail, including their rights, on the Privacy and Candidate fairness pages.

7. Intellectual property

The platform, the case library, the seeded datasets, the golden answers, the integrity tooling, and all related software and content belong to Eigen-Rho or its licensors. Using the service does not transfer any of these rights to you.

The verdicts and hiring decisions a Company reaches using Eigen-Rho belong to that Company. A candidate's own query history and written work remain part of the interview record, which is handled as described on the Privacy page; the hiring outcome belongs to the Company. We do not sell data.

8. Disclaimers

The platform is provided as a tool to support human judgment, and is offered on an "as is" and "as available" basis to the extent the law allows.

The integrity signals are advisory inputs, not an automated hiring decision. They are designed to inform an interviewer, not to replace one.

No proctoring system can detect every form of misconduct. Eigen-Rho does not detect external screen sharing or screen-recording tools, and cannot prevent a determined person from copying what they see. We do not claim or guarantee that the platform will catch all dishonest behaviour. The interviewer's judgment, informed by the available signals, remains central.

9. Limitation of liability

To the extent the law allows, Eigen-Rho is not liable for indirect or consequential losses, or for lost profits, lost opportunities, or hiring outcomes that follow from a Company's use of the platform. Our total liability arising from the service is limited to the amount set out in the applicable pilot agreement. Nothing in these terms limits any liability that cannot be limited by law.

10. Termination

A Company may stop using the platform as set out in its pilot agreement. We may suspend or end access if these terms are broken, if use of the platform puts other users or the service at risk, or as otherwise provided in the pilot agreement. On termination, completed interview records are retained for 12 months after the interview, after which they are deleted, unless your pilot agreement specifies otherwise. This 12-month period is the default, which a Company may change in its pilot agreement.

11. Changes to these terms

We may update these terms from time to time. When we do, we will change the "Last updated" date above, and for material changes we will give Companies reasonable notice through the pilot relationship. Continuing to use the platform after a change means you accept the updated terms.

12. Governing law

[Governing law to be specified in the pilot agreement]
