Codesk.

An online technical-interview platform: a live multi-language code editor with test cases, video recording and proctoring signals, run end to end from one screen.

Codesk online technical interview platform

Codesk lets teams run real technical interviews online, with a live editor, video and integrity signals all in one place.

The challenge.

Remote technical interviews were stitched together from a shared doc, a video call and a separate compiler, with no reliable way to run code, check answers against tests, or trust the work was the candidate's own.

What we built.

We built a single interview room: a multi-language editor that compiles and runs against defined test cases in a sandbox, synchronized video recording, live chat and notes, plus a proctoring layer that tracks focus, tab switches and copy-paste as a timeline the interviewer can review.

The result.

Interviewers now run the whole session, question bank, coding, test cases, video and integrity signals, from one screen, with a full record of how the candidate actually solved the problem.

Under the hood.

  • Live multi-language code editor
  • Run against test cases in a sandbox
  • Synchronized video recording
  • Proctoring: focus, tabs, copy-paste timeline
  • Question bank and candidate management
  • Company, interview and report dashboards

By the numbers.
