You're on call. The database is on fire.

Pick an incident and make the calls. Every wrong move costs minutes; the right ones explain why. 3 incidents, about five minutes each.

How it works

  • Each incident is a few decisions, based on what on-call engineers actually face. All data is made up.
  • Each choice costs time, as it would for real. The best path is the shortest.
  • A wrong move explains what it would really do, and you pick again.
  • At the end you get a rating and a link to challenge someone else.
