Your age does not need to be an issue, as long as you explain why you are applying now and work hard at your application (I work for
ARINGO -
aringo.com - and we helped a 35 year old candidate get into both Wharton and Kellogg this year, with a lowish GMAT, so really: anything is possible!).
Your GMAT is fine, you are an applicant from a rare and interesting industry and being from Italy might be an advantage as well. Your profile is not one the schools see all that often, but having traveled a lot is not that unusual for applicants from Europe, especially if the travels were mainly in Europe, so I would not focus too much on that. You did not mention anything about extra curricular activities, but with such an interesting job, I figure you might have something to add there too, so would rather suggest you think hard about that.
If you are at all open to the idea I would also recommend getting some professional assistance with your application, due to your unusual profile, in order to make you stand out even more, which would of course increase your chances of admission. At
ARINGO, we really do excel at pinpointing strengths of very unique candidates that schools don’t get applications from so often, so I do believe we might be able to help you if you’d like.
Good luck to you whatever you decide to do!
