Features
Everything you need, nothing you don't
Purpose-built for structured interviews. Every feature designed to make running stations effortless and marking precise.
Live Video Stations
Built-in video rooms for every station. No screen sharing, no Zoom links, no tech headaches. Candidates and examiners click once and they're in.
Precision Timing
A shared event clock rotates stations across all circuits. Candidates move, content changes, and timers reset from one central event state.
AI Voice Dictation
Built-in speech recognition with GPT cleanup helps examiners dictate cleaner written feedback without breaking flow during the station.
AI Examiner Assist
Optional examiner support that highlights mark-scheme points mentioned by the candidate to help track coverage. It does not score candidates or make decisions.
Dynamic Content
Station scenarios, images, and questions update mid-interview as rotations advance. Each examiner sees exactly what they need for whoever walks in next.
GPT Feedback Summaries
Generate narrative candidate summaries from examiner scores and written feedback across the stations they attended.
Optional AI Layer
AI tools in Circadian support transcription cleanup, mark-scheme coverage tracking, and narrative summaries. Examiners remain in control of scoring and selection decisions throughout.
Operations On The Day
Timetable and scoring in one workflow
Faculty can move through the programme, open the right room, and keep scoring progress on track without chasing separate systems.
Schedule view
Rounds, breaks, briefings, and one-click room access in a single timeline.

Inside A Live Station
Candidate and examiner views stay in sync
Candidates see the case and join workflow. Examiners see the live station, supporting material, and marking interface without jumping between tools.
Candidate Preview
Candidate view
Candidates can check devices, review the case, and join when the station opens.
Before the station opens
Candidates can confirm camera, microphone, and speaker setup before joining.
Case content visible in advance
Scenario text and clinical images are already on screen when the station becomes live.

Examiner Scoring Panel
Examiner view
Examiners see the live call, station content, model answers, and scoring panel in one workspace.
Everything in one examiner workspace
The call, station content, model answers, domain scoring, and written feedback stay together.
Built for live marking
Examiners can score immediately, dictate feedback, and submit without leaving the station screen.
Timed station flow
Countdown, case changes, and room entry all follow the live event state.
Video and scoring together
Examiners do not need separate tabs for the call, the case, and the score sheet.
Station material in context
Scenarios, clinical images, and supporting prompts stay visible inside the workflow.
Analytics
Insights that drive improvement
From candidate reports to event trends, station difficulty, and examiner calibration, the reporting layer gives programmes a clearer view of performance.

How It Works
From setup to results in four steps
Minimal onboarding. Most teams can configure and run their first event quickly.
Configure
Set up your organisation, define scoring domains, station types, and circuits. Customise everything to match your assessment format.
Prepare
Create stations with rich scenarios, images, and questions. Assign examiners and register candidates. The platform handles room allocation.
Run
Start the event. Candidates rotate automatically, examiners score in real time, and every screen follows the same shared event state.
Review
Review scores, generate candidate reports, and create AI summaries where needed. Export or print when you are ready.
Trust & Reliability
Built for high-stakes assessments
Circadian is designed to help programmes run calmer interview days with reliable delivery, traceable digital scoring, and proportionate security for recruitment workflows.
98% Examiner Feedback Score
Strong examiner feedback from live interview delivery, with particular praise for the smooth running of stations on the day.
Coordinated Multi-Station Delivery
Candidate, faculty, and control views stay aligned from one event engine so stations open, rotate, and close together across the circuit.
Zero Live Platform Failures
No live interview day has been interrupted by a platform-side technical failure to date.
Data Separation by Organisation
Organisation data is isolated with org-scoped permissions and database-level row separation.
Role-Scoped Room Access
Video room access is issued per role and time-bounded to the relevant interview window.
Built-in Tech Checks
Browser, camera, microphone, network, and room-transition checks reduce avoidable issues before the day starts.
Security, Accessibility & Support
Assurance that fits the real workflow
Circadian is built for high-stakes recruitment delivery, with a pragmatic assurance model that protects candidate and examiner data without pretending this is a clinical record system.
Proportionate Security
Designed for recruitment workflows handling applicant and examiner data rather than clinical records, with role-scoped access, row-level security, and time-bounded room access.
Accessible Browser Delivery
Runs in the browser with no installs, plus built-in tech checks to reduce avoidable issues before the interview day starts.
Implementation & Support
Teams can self-serve when they want speed, with optional onboarding, walkthroughs, and live event support available for higher-stakes deployments.
