How it worksStacksInfrastructureSeatsPricing

The playable showcase

Sit where your candidates sit. Then read your own report.

Pick a stack, pick your industry, and we boot you a real sandbox with a genuinely broken system — re-skinned to your world before the email even lands, the same parametric treatment every candidate gets. Fifteen minutes on the clock. When you submit, you see the Candidate Story a tech lead would read: your process record, your own reasoning, and interview questions drafted from your diff.

1 · Pick your poison
2 · Your industry — we re-skin the exercise to it before the email lands

Same sealed code, same hidden tests, different skin — the treatment every one of your candidates would get, which is why a leaked write-up describes an exercise the next person never sees.

3 · Work email — the link and the report go there

Company addresses only — one demo per person, permanently.

The demo records what a real assessment records — the commands you run, autosaves, tab focus — and shows it back to you, which is rather the point. Your code, the record and the report are deleted between 24 and 30 hours after the link is sent. One demo per person, permanently, and one hundred sandbox boots a day across everyone: real compute, honestly budgeted. Your email becomes a sales lead exactly once and is never sold or passed on — see the demo privacy policy.
