Rust Interview Questions & Assessment
Evaluate Rust expertise including ownership, borrowing, lifetimes, trait system, and building memory-safe systems software.
Why Rust Matters
Rust is the fastest-growing systems language, adopted by Microsoft, Amazon, Google, and Meta for performance-critical code. It consistently ranks as the most loved language in developer surveys.
Sample Interview Questions
Explain Rust's ownership model. What are the three ownership rules?
What is the difference between &str and String? When do you use each?
Explain lifetimes. When do you need explicit lifetime annotations?
How does Rust achieve memory safety without a garbage collector?
Implement a generic function with trait bounds. Explain trait objects vs static dispatch.
