Interesting approach. The effectiveness of any AI, especially in nuanced scenarios like interviews, hinges on how well its underlying knowledge is structured. For an 'invisible AI interviewer' to ask relevant, probing questions, it needs more than just data—it requires a structured understanding of the domain.

I've found that applying MECE principles (Mutually Exclusive, Collectively Exhaustive) to knowledge domains dramatically improves AI performance in complex tasks. It ensures comprehensive coverage without redundancy, allowing the AI to navigate concepts more effectively. This seems particularly relevant for assessing candidate depth versus breadth.
