Maybe good oral communication skills are part of these particular requirements? We don't know the details of the interview. But I don't understand why it should be wrong to ask a candidate a question that he should be able to answer and see how he reacts. For some jobs it may even be appropriate to ask questions that the candidate cannot answer and see the reaction. Does he admit that he does not know? How does he phrase it? Is he making things up to cover for his lack of knowledge? And so on.
