The position
Kendor is the first interview platform where candidates use their own AI tools in a secure, online VS Code, and you see every prompt, edit and test run.
Where interviews are going
Google is piloting a code comprehension round: read an unfamiliar codebase, find the bugs, talk through the design, with an AI assistant at hand. That is a Kendor interview, on your own repo.
A reviewed session
A real screen, then its review.
Four steps.
One honest signal.
No question bank, no webcam theatre. Pick a project, let them work, read what happened, advance them.
Pick
A Kendor project or your own repo. Decide if AI is on.
01
Sit
A booted sandbox. Editor, terminal, database and preview.
02
Review
Timeline, playback and an AI summary that checks their claims against the code.
03
Advance
Results write back to the stage in your ATS.
