For the engineer taking the screen

You're being asked to do your actual job for an hour.

No leetcode. No whiteboard. No interview panel watching you flinch. A real editor, a real task, and an AI pair you can lean on as much or as little as you want. Here's what to expect, and what we'll never do.

What to expect

A normal hour of engineering, with a colleague.

  • 1
    A real codebase, a real task
    You'll open a real editor with a real codebase, a brief, and tests that run.
  • 2
    An AI pair, named Lyra
    Lyra helps when you ask, and sometimes asks you questions back. Use Lyra as much or as little as you want.
  • 3
    Your time is yours
    The clock is yours to manage. If something breaks, your work is saved and the clock pauses.
  • 4
    A short conversation at the end
    About 10 minutes walking through your work. Not a grilling — a peer conversation.
What we'll never do

No tricks, no surveillance, no surprises.

  • ×
    Watch your webcam
    Chiron never accesses your camera or microphone. You're assessed on your work, not your face.
  • ×
    Penalize you for breaks
    Step away if you need to. The clock keeps running, but a 10-minute pause is normal — and never flagged.
  • ×
    Trick you for sport
    Lyra is occasionally wrong by design (and you're told this up front). Lyra is never trying to embarrass you.
