Without knowing a GMAT score or a GPA, it is very difficult to evaluate your chances at being accepted. However, regardless of your nationality, grades and scores, it will be challenging to be admitted to a top business school such as INSEAD without any volunteer experience and very limited extracurriculars. Top schools want well rounded individuals who can prove themselves outside of the workplace.
I am sure there are other things that you do in your free time so this may just be a matter of how you frame those activities. I would give some thought as to how to better present this on your application if you want to improve your chances. Or, if you have really done very little in the last few years, I'd suggest getting more involved in your community now!
Best of luck to you!
