Help & FAQ

Do candidates need to create an account?

No. Candidates join via a unique link — no account, no install, no setup required. They open the link in any modern browser and they're in.

What browsers are supported?

Chrome, Edge, Firefox, and Safari (latest two versions). The code editor and design canvas require JavaScript to be enabled. Mobile browsers are not supported for interview sessions.

Can I use Pairlyx for remote interviews?

Yes — it's designed for remote use. Pairlyx does not include video or audio; you'll typically run a call on Zoom, Google Meet, or similar alongside the session.

How do I invite a candidate?

Create a new interview from the dashboard, copy the candidate link from the interview detail page, and send it to the candidate. The link is valid until the interview is cancelled or completed.

What is the system design canvas?

It's an Excalidraw-based whiteboard that opens in the right panel. Both interviewer and candidate can draw, add shapes, and annotate in real time. Toggle it with the canvas button in the room toolbar.

What languages does the code editor support?

You can set the language when creating an interview. Supported languages for live execution (via Piston) include JavaScript, TypeScript, Python, Go, Java, C++, Rust, and more. Syntax highlighting is available for dozens more.

How do I run code?

Click the Run button (or press Ctrl+Enter / Cmd+Enter) in the editor. Code is sent to a sandboxed Piston runner and output is shown below the editor. Execution is rate-limited to prevent abuse.

Can I take private notes during the interview?

Yes. The Notes panel on the right side of the room is visible only to you (the interviewer). Notes are saved automatically and appear in the interview detail page after the session.

How do I end the interview?

Click "End interview" in the room controls. This saves a snapshot of the final code and canvas state, marks the session as completed, and redirects you to the review page.

How does the AI review work?

After the interview ends, you can request an AI review from the interview detail page. Pairlyx sends the final code snapshot to Claude (Anthropic) which generates a structured assessment covering code quality, problem-solving approach, and a hiring recommendation.

Can I edit the AI review?

Yes. Every section of the AI review is editable. Open the full review editor, make changes, and click Save. Once you're satisfied, click Finalize to lock it as a read-only record.

Is the AI review a final hiring decision?

No. The AI review is an assistive tool to help you structure your evaluation. Hiring decisions should always involve human judgment. See our Terms of Service for more detail.

How long does the AI review take?

Usually 15–45 seconds. You'll receive an email notification when it's ready (if notifications are enabled in your profile settings). The page updates automatically via a live status indicator.

How much does Pairlyx cost during beta?

During the beta period, all features are free with no interview limits — code editor, canvas, AI review, templates, and team members are all included.

Will there be paid plans?

Paid plans (including Pro with advanced team features) will be introduced after the beta period ends. Existing beta users will be notified well in advance.

Can I add team members?

Yes — team members are free during beta. Go to Dashboard → Team, enter your team member's email, and they'll receive an invite. Team members can view and run interviews created on your account.

The editor isn't syncing in real time — what should I do?

Check your internet connection first. Real-time sync requires a stable WebSocket connection. Try refreshing the page; the session state is persisted server-side so no work is lost. If the issue persists, check that no browser extension is blocking WebSocket connections.

Code execution isn't working

Code execution goes through our Piston runner. If it's unresponsive, it may be temporarily overloaded. Wait a moment and try again. Rate limits apply: up to 30 executions per minute per session.

I didn't receive the AI review email

Check your spam folder. You can also enable/disable review notifications in Dashboard → Profile → Notifications. The review is visible on the interview detail page regardless of email delivery.

The canvas isn't loading

The design canvas loads a separate module. If it appears blank, try toggling it off and on with the canvas button. If the issue persists, a hard refresh (Cmd+Shift+R / Ctrl+Shift+R) usually resolves it.
