Top Law Schools

How common are interviews for these schools?
Are most eventually admitted applicants interviewed or is it something they do for the applicants they're less sure about?

Any info on T6 interviews appreciated!

Y/S do not interview
H interviews candidates before admissions offers (how many get interviews vs. ultimately admitted is the subject of endless speculation)
UChi interviews
Columbia interviews some candidates (consensus is it's for borderline or scholarship candidates)
NYU does not interview for admissions
