Frequently Asked Questions by Hiring Teams
Everything you need to know about candidate integrity, sandbox security, and volume billing.
Topfolio deploys a multi-modal anti-cheat engine directly in the browser: 1) Face Mesh AI continuously verifies facial geometry and flags multi-face or absence events; 2) Fullscreen lock detects tab switches and DevTools attempts; 3) System-level clipboard protection prevents external code pasting; 4) Audio analysis flags background conversations. Every anomaly is logged with timestamped cryptographic evidence and factored into an objective 0–100% Trust Score.
Yes! Unlike legacy proctoring tools requiring bulky Chrome extensions or desktop executables that candidates refuse to install, Topfolio runs 100% natively in modern web browsers (Chrome, Edge, Firefox, Safari) using standard Web APIs for camera, fullscreen, and audio permissions.
Yes. Growth and Enterprise plans allow you to provision custom PostgreSQL schemas (e.g. your sanitized e-commerce, fintech, or healthcare tables) and configure customized test suites with custom evaluation rubrics and automated test assertions.
No. All Topfolio assessment credit packs have lifetime validity and never expire. You can purchase a 100-credit pack today and use it over 6, 12, or 24 months as your hiring needs fluctuate.
Our stateful autosave engine continuously persists code drafts every 3 seconds to cloud storage. If a candidate is disconnected, they can seamlessly reconnect with their secure invite link, and the proctoring engine logs the outage timestamp without falsely flagging it as a violation.
Topfolio supports automated webhook triggers that push candidate scores, trust ratings, and PDF scorecard links directly into Greenhouse, Lever, Ashby, Workable, or custom Slack/email webhooks upon test completion.
