I wonder: if a LLM can answer typical interview question better than a human, what kind of questions should we ask so that using a LLM becomes worthless? Something that LLMs are forbidden to talk about? Something that LLM doesn't know well? In my experience, LLMs are pretty bad with low-level languages like Rust/C when you need to deal with pointers and ownership, avoid extra copies. Another option is to ask for something impossible, as LLMs usually do not admit inability to solve the problem and prefer to hallucinate a fictional solution.
