How this challenge is graded
You work as a junior software engineer, and these four criteria are published before you start.





Recruiters read the same skills list hundreds of times. A line of text can't show how you think, and nobody can check it.

Each challenge leaves a record: the brief, the rubric, your score on every criterion and the date. Proof you can point to.

Feedback from the grader

It names the missing winter months. Add how that gap is likely to move the error.
Clear and short. Lead with what the grid operator should do with the forecast.
