I am still a junior but this seems like you are interviewing the AI rather than the candidate. Also why bother with a technical interview if you expect AI to do their job?

Actually not a real technical interview for this case, it's a real world problem solving, including business analysis(for the uncleared problem), coding, and testing to deliver to me. What I'm looking for a individual builder(or a one-person tech team) instead of an expert on a specific tech stack.

It's interviewing the capacity to use the tools in a useful manor rather testing the tools themselves.
