Overview
What this challenge is about.
Optimizing Inventory for a Barcelona D2C Cosmetics Brand. Beginner-friendly challenge in code. Writing production code that solves real engineering problems,...
The Brief
What you'll do, and what you'll demonstrate.
How can Glow Naturals use historical sales data to set inventory levels that minimize stockouts and overstock?
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
