Ten minutes inside the job you want. Real decisions, an honest read on how you did, and proof you can keep.

One workday — an on-call engineer's night — unfolds in ten beats. Here are four of them.
A payments service is throwing errors and the dashboard is red. You are the one who is awake.
Read the logs or roll back first? You choose where the only ten minutes that matter get spent.
Ship the hotfix, or roll back and buy time. Devi is on the thread waiting for your call.
The incident is closed. You write what happened for the team — plainly, and without blame.
Pick a role and play its days in order — an on-call night, a release call, a code review. Each one built from the real thing and reviewed by people who do the job.
Candidates who finish a day can share it with you — their decisions, their words, their scores.
Which days get finished, where scores land, and which schools show up first. Every rate is written as a sentence, every bar carries its number, and everything here is aggregate: individual work stays behind each candidate's consent.
Same honest day — the student lives it, your team reviews it.
No card, no timer. Play one workday tonight and see where you stand.
