Camera, microphone, and fullscreen are required during the assessment; media is not recorded or sent. Leaving fullscreen or hiding this page (including by switching tabs, minimizing, or switching apps) disqualifies this local demo attempt. Browsers cannot tell which action hid the page. Tests run locally in a restricted browser sandbox. If you use AI chat, your question, recent chat, and currently open TypeScript file are sent through this app to Google Gemini 3.6 Flash; no other workspace files are included. This demo makes no hiring decision.
