Gronex is an interview preparation platform focused on backend and machine-coding rounds. Instead of submitting a function against hidden test cases, users work inside a full repository in a browser-based workspace: reading existing code, locating the defect or missing behaviour, editing multiple files, and running the project's test suite until it passes.
The catalogue covers repository implementation, concurrency and race conditions, incident debugging, API contract debugging, database engineering, runtime diagnostics such as heap dumps, GC logs and thread dumps, and Linux and shell fundamentals. Problems are available in Java, Python, Node.js, C++ and Bash. A subset is free and can be run without an account.
Additional features include system design walkthroughs, guided learning paths, a weekly timed challenge, an AI mock interviewer that asks follow-up questions after a solution passes, and a separate product for companies to run live technical interviews on the same repository problems.

Are you sure, I got a link to a codingame.com assessment from block. Source: about 3 years ago
This, and OP should practice handling the stress. Find a friend to do interviews with, or give yourself a timer, or whatever. codingame.com is a good alternative if you want to try dealing with a timer and don't want to be able to cheat. Source: about 3 years ago
Just jumped to codingame.com and start (cant) solving puzzles. Source: over 3 years ago
Personally, I like codingame.com (completely free unless you are an employer) - Their simple puzzles are great places to get an idea of how programming works and the kinds of problems they solve. I think the first puzzle I was able to solve as a beginner in a few days. Source: over 3 years ago
I believe it's possible to use rust in codingame.com. Is that ok for you? Source: over 3 years ago
