For most of the schools you can download a pdf of the recommendation form (from the school website) in case your recommenders can't submit electronically and have to mail it in. I wonder how much longer that will continue given everything else is electronic though.

From what I can tell, they ask a range of short answer questions and then also have the recommender evaluate the applicant on a range of criteria. I didn't apply to Harvard/Stanford/Wharton so I don't know what those are like.

Here are a few from some of the schools I applied to this past fall.

Berkeley Haas: https://mba.haas.berkeley.edu/LORFall2010.pdf
Kellogg (this one is from '09 though): https://gmatclub.com/forum/download/file.php?id=6315

If you do a google search and poke around online you should be able to find the documents.

Amazing thank you! I'm looking at the Haas form right now... this is more comprehensive than I thought it would be. This is great thanks
