Gronex
Backend interview prep in real repos, not algorithm puzzles
LeetCode trains you for algorithms. Real backend rounds hand you an unfamiliar repository and ask you to find the bug and make the tests green. Gronex is practice for exactly that, in your browser, with no setup. Java, Python, Node.js and C++. Concurrency races, database incidents, API contract bugs, heap dumps and GC logs. Free problems run without an account.
Hi Product Hunt. I built Gronex after watching strong engineers grind hundreds of algorithm problems and then freeze when an interviewer handed them a repository and said "this test fails, find out why." Those are different skills. Gronex problems are whole repositories, not single functions. You open a real project in the browser, run the tests, and work until they pass. Concurrency races, database incidents, API contract bugs, heap dumps and GC logs. Several problems are free and run without an account, so you can judge it quickly. Happy to answer anything about how the problems are built.
