AI Overlay for Byteboard Interviews on Mac

Updated October 2026 · 3 min read · Tested with LockDown Browser v2.1.6.01

Byteboard spun out of Google to replace whiteboard-style coding interviews with project-based assessments graded against a structured rubric. Candidates open a browser tab, work in a VS Code-style IDE, and submit a design doc plus a coding project that human graders score across roughly twenty software engineering skills.

Byteboard ships two products: CoreEval, the async take-home, and CodeCollab, the live pair-programming room. Neither product installs a desktop app or kernel hook. CoreEval is timed but unmonitored beyond the IDE itself, and the graders see your submitted code plus a transcript of in-pad events, not a video of your machine. CodeCollab is a synchronous VS Code-based editor where an interviewer joins the same multi-file workspace and watches your edits in real time.

No. CoreEval is a browser pad that records edits, runs, and pastes inside the pad itself.

CoderPad-style paste detection fires when text is inserted into the editor from the system clipboard.

No. The CodeCollab interviewer joins the same browser-based workspace and sees the shared IDE state.

No. The entire experience is web-based.
