Both interviews looked pretty like job interviews:
1) discussed my employment history
2) why MBA, why INSEAD, why now?
3) my career plans
4) any questions?
I waited 4 or 5 days for the second interviewer to reply (ok, they are very busy people).
My background:
GMAT: 750 (Q47, V47)
Work experience: 6 years, financial controlling (supervised 15 people at my last job)
International exposure: backpacking around the world, worked in an expat team for 1.5 years.
I look forward to the final decision.
