Custom Calibrated Track

Tell us about the stack we are building for.

This form opens the scoping for a Custom Calibrated Track — a genuinely broken system that looks like yours, built by our engineers as a timed, gradable challenge and proven through the same harness as the public library. Sealed to your workspace, calibrated before your first candidate sees it.

A company address — the workspace is set up on your domain.

Your custom track

Comma-separated is perfect: “Rails 7, Sidekiq, Postgres”.

No proprietary code here — that comes later, under NDA, if we proceed. This is just enough to bring an engineer to the call.

What you enter here is used to reply to you and for nothing else — how we handle it.
