What Is OnlineInterview.io and What Can You Do With It?

Updated

OnlineInterview.io is a free, browser-based platform for running remote technical interviews. It combines a runnable code editor, embedded video chat, and a shared drawing canvas in a single room that you create with one click and share by link. It fits teams, agencies, or universities that want to screen and interview candidates without stitching together a separate meeting tool and coding environment. Each room supports up to three users at once — for example, one candidate and two interviewers.

What the platform includes

The site describes five core capabilities:

Feature What it does
Online code editor Write code collaboratively in the browser, choose a language, provide program input, run it, and check the output
Embedded video chat Talk to remote participants directly in the browser, without a separate meeting application
Drawing canvas A shared board for explaining concepts and sketching ideas
Dark / light mode Switch themes the way you would in an IDE
Session download Save the code and the drawing canvas image to your computer

The editor supports C, C++, Go, Java, JavaScript, Julia, Kotlin, Lua, Python, Ruby, Rust, and TypeScript, with syntax highlighting and a REPL. The site positions the product for recruiting, screening, and hiring, and describes itself as a free virtual recruitment tool with an online code editor and embedded video chat.

How a session works

  1. Create a room. Use the one-click "Create Free Room" action on the site.
  2. Share the link. Send it to the candidate and any other interviewers.
  3. Interview together. Talk over the embedded video chat, write and run code in the editor, and use the drawing canvas when a diagram helps.
  4. Save the session. Download the code and canvas image at the end if you want a record.

The expected result is a live session where all participants see the same code and drawing surface while talking in the same browser window.

What to keep in mind

  • Room size is capped at three users. That suits one candidate plus two interviewers; larger panels would need a different setup.
  • The site presents the platform as free, but the available material does not detail account requirements, limits, or terms beyond that. Check the site's own pages before relying on it for a high-stakes interview.
  • The editor runs code in the browser with program input and output, which covers algorithm and scripting discussions well; it is not described as a full project environment.

If your need is a lightweight, link-based coding interview with video and a whiteboard for a small panel, this platform matches that use case directly. If you need more than three participants or a persistent interview record beyond a manual download, plan around those constraints first.
