Renewed Vision Software Engineer interview questions

For a Rust SWE role. In the initial interview, the HR person asked a lot of niche Rust syntax questions, but they had no clue what the answer was and were clueless/unable to discuss the questions or clarify. They were apparently recording it to show to the hiring manager. This interview was over 5 months from when I had applied (I had heard nothing until they randomly asked for an interview). Crazy way to do interviews. Would not recommend.
