Also finished my interviews.
Both were around 1 hour long, 1/3 in English and the rest in Portuguese.
The questions were very similar too:
1st interview: tell me about yourself, why MBA, accomplishment, failure, international experience, application to other schools or not, questions
2nd interview: walk me through your resume, accomplishment, international experience, why MBA, why INSEAD, application to other schools or not, questions
No feedbacks were given and I'm pretty anxious.

Cheers.
