Go & Rust Competence Check

Five questions from memory. No sign-up, no email — see the gap between what your résumé claims and what your brain can retrieve.

Go and Rust represent the modern systems-programming frontier. Go optimizes for simplicity and concurrency with goroutines and channels, while Rust's ownership model eliminates entire classes of memory-safety bugs at compile time. Together they power the cloud infrastructure and performance-critical software that the internet runs on. This skill measures fluency in the languages — and the mental models — behind modern backend and systems engineering.
