I actually found this quite helpful and refreshing. Tired questions in interviews can get depressing as you hear yourself say the same things.

I have said I'm a perfectionist in the past, but in honesty there was some truth to it, I learned over time to let it go for my own sanity. However, I take your point.

It is also helpful to have someone really guide a show don't tell question, as sometimes it is hard to show in an interview situation.
