I second that to some extent. I think, at Ross, an interview invite is not a huge indicator of an admit. Especially in a year like this, when app volumes are astronomically high and the quality of apps better, schools can afford to interview a larger pool of "likely" candidates to admit from.
Also, not everyone will enter an interview at the same level. Ross probably has a likely short list of admits by now and the additional data point from the interview will shuffle that list only so much.
Going by historic numbers, 40%-50% seems to be the post-interview admit rate. Once again, based on the app volume, you have to feel happy about those odds.

I think its best to be skeptical till the admissions decision. Seeing so many Indians getting invites makes me think that its going to be one hell of task to get thru.
