The position

Kendor is the first interview platform where candidates work live with Claude/Codex in the terminal, 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.

Four steps.
One honest signal.

No question bank, no webcam theatre. Pick a project, let them work, read what happened, advance them.
