Actually... not a fan of the name CandidEight. The term "candidate" stirs up in the mind political figures, not so much professionals.
I also think the use of "eight" meaning 8 questions is limiting. Why only 8 questions? Why not more? Why not less? Why not as many as people want, whether that be practicing one question that is a tough one every time, or many questions? The number 8 for you is only a gimmick and while gimmicks aren`t necessarily bad things, they don`t get you as far as good content will. Don`t limit your content because of a number.
I like CandidEight because it`s clever. I just don`t think it fits.
