I can see how some of them might be legitimately hard to answer, mainly the last 3, because there are so many variables and a lot might really depend on the actual relationship, but even there she still could have given partial answers or demonstrate willingness to explore the issue, but a refusal&cop-out answer signal the opposite. And should definitely have answered the ones about your specific issues, I mean surely it's sensible to make sure the professional you're about to hire has experience with the thing you're hring them for?
