How to Start a Remote Coding Interview Session on OnlineInterview.io

To start a remote coding interview on OnlineInterview.io, open the site and use the Create Free Room button to generate a virtual room with one click, then share the room link with your candidate and any co-interviewers. The room supports up to three participants at once, and everyone works inside the same browser session using the code editor, embedded video chat, and shared drawing canvas. No account setup is described on the site, so the room link itself is what you distribute to participants.

What you need before the session

• A modern browser on each participant's machine (the editor and video chat run in the browser).
• The room link, which you create and send to the candidate and interviewers.
• A plan for who joins: the site states a shared room allows up to three users at the same time, which fits one candidate plus two interviewers.
• Any program input you want to test, if you plan to run code during the session.

Step-by-step: running the session

1. Create the room

On the site, select Create Free Room. The page describes this as a one-click action that produces a free virtual room. You do not need to configure a meeting tool separately.

2. Share the link

Send the room link to the candidate and the other interviewers. Because the room is shared, everyone who opens the link joins the same session.

3. Confirm everyone is connected

Use the embedded video chat to talk directly with remote participants. The site positions this as a replacement for separate meeting software, so you can verify audio and video before the technical portion begins.

4. Pick a language and run code

In the code editor, choose a programming language, write or paste the problem, provide the program input, run the code, and check the output. The editor includes syntax highlighting and works as a REPL in the browser.

Supported languages listed on the site:

5. Explain with the drawing canvas

When a concept needs a diagram — an algorithm sketch, a data structure, a system design — switch to the shared drawing board. It is visible to everyone in the room, so you can annotate while discussing.

6. Save the session

Use Download Session to save the code and the drawing canvas image to your computer. This gives you a record of what was written and drawn during the interview.

Verification and common snags

• Check the participant count. If a fourth person tries to join, the three-user limit applies; decide in advance which two interviewers will attend.
• Test code execution early. Run a trivial program with sample input before the candidate joins, so you know the language and input fields behave as expected in your browser.
• Confirm the canvas is shared. Draw a quick mark and ask the candidate to confirm they see it before relying on diagrams.
• Switch display mode if needed. The site offers dark and light modes, which you can toggle like a programming IDE — useful if screen sharing or recording looks better in one mode.

What the platform is suited for

OnlineInterview.io describes itself as a free remote tech interview platform for recruiting, screening, and hiring, used by companies, agencies, and universities. It combines the three things a live coding interview usually needs — an online code editor that runs code, video chat, and a shared drawing board — in one browser room. It is a reasonable fit when you want a lightweight session without installing separate meeting and coding tools; if your process requires more than three participants in a single room, the stated limit is the constraint to plan around.
