National Machine Coding, LLD and Production Debugging Contest Gronex

Gronex Engineering Cup #1 is a free, online, 2-hour competition for students and engineers, focusing on practical software development skills. Participants will solve three brand-new problems within real code repositories in their browser, with automatic grading against a real test suite.

The contest covers machine coding, low-level design, and production debugging, allowing solutions in Java, Python, Node.js, or C++. Scoring is based on the percentage of test cases passed, with hidden tests revealed during grading. Prizes include cash, swag kits, and Gronex Pro access, along with a verifiable certificate of participation for everyone. Top performers receive a Certificate of Merit. The event is organized by Gronex.
