Maybe a bit overdone, but I think in between lines the interviee well knows the intended solution to the question and is just toying with the interviewer to make a point, much like a cat playing with a barely dead mouse

I couldn't interpret it any other way, really. The interviewer is asking the interviewee to be "clever", but the cleverness of the interviewee is to choose a common-sense solution and expose the artificiality of the questions, thus the low quality of the interview. (Common sense solutions should usually be the first choice, after all.)
