How does the collaborative editor work?

You and the candidate share a single editor with live cursors. Edits sync in real time, so you can pair on a problem together instead of watching a screen-share.

Can candidates run their code during the interview?

Yes. Code runs in the session and the output appears instantly across 20+ languages, with no local setup for you or the candidate.

Can I review interviews afterward?

Every session can be played back, so teammates can review how a candidate worked through a problem without having to attend the interview live.

Is there a whiteboard for system design?

Yes. You can switch to a shared real-time whiteboard for architecture and system-design rounds, all within the same session.

Do candidates need to install anything?

No. Candidates join from a link in the browser. There is nothing to install and no account to create.

Interview like you pair program

Live coding interviews in a shared editor

Forget awkward screen-shares and clunky setups. Run live coding sessions where you and the candidate write code together in the same editor, in real time.

Why teams interview with CoderScreen

Truly collaborative

20+ languages

Interview in whatever language fits the role, with syntax highlighting and autocomplete built in.

Run code live

Execute code during the session and see the output instantly. No local setup, no sharing screens.

Review afterward

Every session can be played back, so the rest of your team can review the interview without sitting in on it.

One tool, not five

Editor, whiteboard, AI assistant, and recording in a single product. Nothing to stitch together.

Open source

A whiteboard for system design

Switch to a shared whiteboard for architecture and system-design rounds. Sketch boxes and arrows together without leaving the interview.

Shared, real-time canvas
Great for system design and architecture rounds
Stays in the same session as your coding round

AI assistant and private notes

Keep an AI assistant on hand for follow-up questions and jot private notes only your team can see while the interview runs.

Private notes the candidate never sees
AI assistance for follow-ups and hints
Full session playback to review later

How do I handle the edge case when the input array is empty?

Add an early return guard at the top of the function:

if (!nums || nums.length < 2) {

return [];

}
