Hi Javier and thanks for your inquiry.
Thanks for the chuckle about lulling me to sleep. I think I needed that to help keep me going this Saturday morning!
First of all, with a 700+ GMAT, you will clear the academic qualifications hurdle. You also have some good international experience for the 2 schools you have focused and this can certainly be spun to your advantage.
I like the career progression and I can tell you from first-hand experience that admissions committees really **love** the rotational type work you did at Endesa. Your extracurriculars also look impressive, particularly if you have been able to maintain a decent level of involvement over the past few years.
With well-prepared applications that contain outstanding reasons for why an MBA, diversity, etc as well as some good ‘wow’ factor, you would be an extremely competitive applicant at Columbia and INSEAD.
I don't believe in putting pressure on individuals, but since you specifically asked, I'd focus hard on the GMAT. CBS shows rather low leniency towards applicants more than 30-40 points below the average accepted GMAT score.
Other than your GMAT, you just need a good differentiating story that contains a good 'wow' factor. Your other prerequisites are pretty strong.
Best of luck with your applications!
Sincerely,
David Petersam
