Hello Harsimran86, thanks for your question.
Your GMAT is fine, but your GPA might be a bit low. That could be a challenge but is not insurmountable. Do you have any other analogue that is a better representation of your academic ability and potential? If so, briefly cite this in the optional essay.
Your competitiveness will come down to the quality of your work experience. Can you draw upon “moments” when you truly led: influenced individuals and organizations, drove results, took initiative?
Your extracurriculars could also be a challenge. Outside of formal volunteer activities, how do you engage the world? If you can discuss your interests and passions and show the admissions committees how you take initiative, lead, and collaborate in those arenas, you could mitigate the lack of your formal experience in this arena.
In terms of your post-MBA goals, paint a picture that cohesively ties together your past, present, and future. Demonstrate to the admissions committees that your desired career path necessitates an MBA.
Given the potential GPA and extracurricular challenges, I think Wharton, Columbia, and INSEAD would be reaches. I am not familiar with the International Organizations MBA from Switzerland. Most programs do place their placement statistics online.
Best of luck,
