What the L7 Loop Weighs

  • Design answers are held to at least the staff bar, so cover scale, failure, and how the system evolves.
  • Domain depth matters more here than at any lower level.
  • Leadership stories should show direction you set for several teams and the results.
  • Ask your recruiter early which rounds your loop includes.
