Thanks for the detailed info. Since it is common in Sweden to take a 1-2 year gap between high school and college, I do think that the ad coms will consider your work experience during that time; however, since you only worked roughly 2 years full time, you may want to wait until you have another year or two of full-time work experience under your belt to apply. Alternatively, you could apply now and then reapply in a couple years if you do not get in.
I think you'll have plenty of stories to demonstrate leadership between your experience at TNS and your college activities. Your academics are quite strong, so that is great. There are only two gaps in your profile: 1) lack of community service activities and 2) lack of post college work and life experience. You could overcome the former, but I am not totally sure how they'll handle the latter at any of your target schools.
Generally speaking, the ad com seeks candidates with 3-5 years post-college work experience and who have kept up their extracurriculars, community and leadership activities while working. In your case, you'll be relying mostly on stories from university for extracurricular and community work, which is not the ideal. There are some universities though that are starting to welcome younger students (HBS, Wharton are among them), but those candidates have to have done extraordinary things in undergrad to be admitted.
I think you'd have a much better shot at these schools if you did continue at TNS in a full time capacity for a year or two post-college, and during that time take a leadership position in some kind of community organization that you are passionate about. And of course, keep up with the soccer coaching, etc. If you did these things, I think your profile would be pretty competitive at those schools. If you're eager to apply sooner rather than later, there is no harm in calling the ad coms at these schools and asking their perspective about your lack of post-college full time work experience. Your targeting the right level of schools, it's just a matter of your experience level.
Hope this helps!
