If you're dinged you'll find out on the 28th of Feb.
"The Admissions Committee will release interview invitations between Thursday, January 26th and Tuesday, February 28th. Due to the nature and complexity associated with the admissions process there is no particular order in which invitations are released. Also on February 28th, the Committee will release all final admissions decisions to candidates that are not being invited for an interview and therefore no longer being considered for admission.
If you are invited for an interview, you will need to complete your interview by Friday, March 9th. Interviews will be available on campus with second-year Wharton MBA Students who are full members of the Admissions Committee and off campus in various "Hubs" around the world by Admissions staff members. All interview options are equally considered within the admissions process."
