I thought these were all very relevant questions. Fit is everything, and presumably they already have the candidate's resume / portfolio to review, so they're digging into more qualitative stuff
Fit of what to what? If it's a fit of candidate to the event, then YC doesn't have information about potential applicants. If it's a fit of somebody already well inside YC circle, then that should be stated - but I don't think YC would limit their intent that much, even though the size (120 people) suggests otherwise.
So, no, I don't think this kind of fit is good here.
