I agree with this. One way or another, as an interviewer I need to know what your skill/experience set is. Skills/experience can always be developed, but that should be a known factor at the point of hire.
One positive point that TFA made was the need to 'Listen Carefully and Answer on Point'.
As someone who interviews regularly, I cannot count the number of times that interviewees have not followed this simple advice. To the question "Give an example of when you last frustulated a gibbet..." they will describe in detail their general thoughts on the many finer points of gibbet frustulation, but not actually give an example.
Also, be "Concise and Offer Details on Demand"
Top tip: when you have finished answering a question, stop answering the question.
