International accounting

I don't know how many people here know about this area, but I'll ask anyway.

I'm still very young, and I finished my bachelor's at an Ivy league school recently. Unfortunately, I literally had little to no clue about getting a job, and purely followed my academic interests. It hasn't gotten me anywhere, and I'm still trying to get a decent job to this day. Internships with any financial work or entity is nonexistent; nothing but clerical work really. I am networking pretty hard right now, but it does have its difficulty for reasons I won't get into here.

My interests stem from mathematics, so I did a bit more of that in school, but unfortunately also a few too many needless economics courses. I did one class each in accounting and finance, and although I appreciate some aspects of finance, I have no interest in some of the job types (i.e. private equity, sales and trading), or could not see myself working some of obscene hours for those jobs on a regular basis.

Accounting, however, did peak my interest a bit more, but I seriously lack the knowledge and credits in it for any kind of related job at this time. I'm seriously considering attending school again to help myself move forward with actually starting a career in international-based accounting because of its potential flexibility. Is business school the most optimal route, or should I get the credits and certification another way?

Just reading this site for a few minutes has already taught me a lot more than any counselor at my alma mater. I wish I had seen this a few years earlier.
