I interviewed this morning with an Adcom over Skype and was waitlisted later in the day...talk about turn around time
The interview lasted about 30 mins. Very friendly tone, but the emphasis was on Why Cornell? I guess they are really looking for a perfect fit given their small class size. Also, maybe my truthful answer to the question "What other schools are you applying to and what is the status?" got them thinking that i wasn't serious about Cornell or was using them as a backup.
Anyways, my advice would be to research your future goals (coz she did ask for specific companies that i would be interested in after the MBA) and be sure to "sell" your fit to Johnson. Those were the main themes of the interview.
Good luck to everyone waiting..
