Overview
What this challenge is about.
Forecasting Model for Online-Game Daily Active Users. Advanced challenge in code. Writing production code that solves real engineering problems, earn a block...
The Brief
What you'll do, and what you'll demonstrate.
Forecast DAU 14 days ahead per region with MAPE beating the finance-team spreadsheet baseline.
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."
Earning criteria — what you'll demonstrate
- Apply both classical and ML approaches to time-series forecasting
- Use rolling-origin cross-validation for honest forecast evaluation
- Engineer time-aware features (lags, calendar effects, event indicators)
- Operationalize forecasts for live-ops decision-making
