AiFA Labs Rust Engineer interview questions

Interviewed for a Rust Developer role at AiFa Labs and cleared two technical rounds covering Rust fundamentals, ownership/borrowing, lifetimes, smart pointers (Box, Rc, Arc), Mutex, traits, trait objects, static vs dynamic dispatch, async/await, Tokio, multithreading, Linux concepts, and coding problems such as implementing a MinStack with O(1) get_min. My salary expectation was communicated before the interview process began. After clearing the rounds, compensation discussions kept moving downward and eventually fell below my previous compensation. I was then informed that the position had been closed. Feedback: The technical interviews were good, but compensation budget and candidate expectations should be aligned before conducting multiple interview rounds to avoid wasting time for both candidates and the company.
