How Enum Works
Production-style simulations that train you for real engineering work
1. Choose a track
Select from Frontend, Backend, Linux, or System Design. Every simulation mirrors a real-world scenario.
2. Investigate & debug
Access a live terminal, read logs, edit code, or design architecture graphs inside an interactive sandbox.
3. Verify & deploy
Submit your solution. Our automated tests evaluate your code or design instantly to award XP.
