INSEAD 2013 JAN - Calling All Applicants

Well I'm not AdCom so take my reply with a pinch of salt - but what they mean most likely is that the AdCom post the interview will compare the 'paper you' (from your app) and the 'real you' (from interviewer feedback) and then take a call on the admission if you come out true-blue.
They would have obviously seen your file earlier in order to shortlist you, but this round could be different people or different questions scanning both sets of reports.
This is also the stage at which 'class diversity' plays an important part. For example, I've spent 3.5 years in consulting and INSEAD is a very consulting heavy school. So I was told by my interviewer at the end of my first interview that 'I think your values and those of INSEAD are generally aligned but now it remains to be seen how you can differentiate yourself from the huge consulting applicant pool'. Another example is that INSEAD usually limits students from any one nationality to 10% of the total class size in order to maintain the international diversity. This means that Indians and Chinese face tougher competition. Again, this is where they would weed out some candidates.
I'm 24, Indian, with 710 GMAT and consulting - those things may have worked against me because they're not strong differentiators (age is in fact much lower than the average 29).
But what probably worked for me is that I'm a woman (sorry guys!) and that I really passionately wanted to go to INSEAD because I like the school and what it stands for.
I don't think you should worry too much about how they are going to perceive you - stick true to your value system, and what you can do for INSEAD. It'll all work out for the best.
