Undergrad in business, GPA 3.2.
You do know that both your GPA and your GMAT are below average at all 4 schools - Columbia, INSEAD, Booth and Wharton, right?
Where did you go to school? Did you attend an Ivy or equivalent? What does your work experience look like? Did you work at a "blue chip" firm such as McKinsey, Google or Goldman Sachs? Were you a military officer?
What are your extracurriculars?
Based on your GMAT and GPA alone, you are a stretch candidate at those 4 schools. I'll defer to an MBA admissions expert though. Please feel free to correct me if I'm wrong.
I'll tell you right now that I'm in approximately the same boat as you, I have a bit lower GPA but a higher GMAT, I'm a Marine officer currently with 15 direct reports, working in a job that was formerly occupied by an officer 2 ranks senior to me; and I don't think I'm a "strong" candidate at your 4 schools. Especially Wharton.
There are guys out there with 770 GMATs, 3.8 double major from Stanford, and worked 4 years in McKinsey applying to some of those schools.
