Platform

Everything your hiring loop needs

Purpose-built modules for every stage of the interview — from scheduling and real-time collaboration through evaluation and committee reporting.

Collaborative editing

Two or more people write code in the same Monaco editor. Cursors appear in real time, edits merge within two seconds, and there's a built-in chat alongside the code.

  • Multi-participant editing
  • Cursor and selection sync
  • Vim and Emacs keybindings

Sandboxed execution

Code runs in isolated containers with CPU and time limits. Candidates test against visible examples while you judge against hidden suites across seventeen languages.

  • Judge0, Piston, or Docker backends
  • Visible and hidden test suites
  • Per-case timing breakdown

Interview integrity

Assessment lockdown keeps the candidate in fullscreen until submission. Tab switches, paste events, and focus changes get logged into a severity-scored timeline.

  • Fullscreen lockdown mode
  • Camera capture and recording
  • Complete activity audit trail

AI-assisted evaluation

After submission, an AI review scores code quality, estimates complexity, flags potential plagiarism, and produces a structured recommendation for your committee.

  • Code quality scoring
  • Complexity analysis
  • Hire or pass recommendation

Access control and tenancy

Clerk authentication with seven roles enforced on every route. Each organization's data stays isolated, and every action writes to an immutable audit log.

  • Seven RBAC roles
  • Organization-level isolation
  • Immutable audit logs

Scheduling and reports

Calendar scheduling with automated invitations and reminders at twenty-four hours, thirty minutes, and right before the session. Reports export as committee-ready PDFs.

  • SMTP email notifications
  • Automated reminder cadence
  • PDF report export

Workflow

From invitation to hiring decision

Three steps. One platform. No context switching.

  1. Schedule and invite

    Create a session, pick a question from your bank, and share a secure link. The candidate joins without needing an account. Reminders go out automatically.

  2. Interview live

    Collaborate in a shared editor. Execute code against hidden test suites. Review camera feeds. Take private notes and score the candidate as they work.

  3. Decide with evidence

    Generate a report with scorecards, AI review, the best submission, and the full integrity timeline. Hand it to your hiring committee ready to go.

Security & governance

Enterprise controls, on by default

Built around OWASP guidelines with layered authorization, tenant-level isolation, and full auditability. Security review becomes a checkbox, not a blocker.

  • Clerk authentication with SSO
  • Role-based access on every API route
  • Organization-level data isolation
  • Zod schema validation on all inputs
  • Rate-limited code execution
  • Immutable audit logging
  • Encrypted managed Postgres
  • Assessment lockdown mode
