Sorry I'm slow in responding the earlier questions. My classmates are amazing, they have a really broad range of experience and are incredibly intelligent and hard-working. Out of 21 of us, 11 are international students (from Pakistan, China, Nepal, Switzerland, Belgium, South Korea, the Dominican Republic, and Bolivia) and 10 from the U.S. Many have finance or consulting backgrounds, including consulting for developing countries, but we have someone who came from the DoD, one from DoJ, a former Kiva fellow, some people with start-up experience, and even a former engineer. The small class size definitely helps, we all know each other really well and help each other get through the courseload, which is heavily quantitative (at least in the 1st year) and very demanding.
The program is a mix of quant-heavy skills courses and IR, which is a unique combination and one that I find really interesting and applicable to a wide range of careers. For pre-reqs, I would just apply and if you're admitted but need to fulfill one, they'll tell you and you can take it over the summer. If anyone really wants to know about course specifics or syllabi, just message me and I can try to answer your questions or send you a syllabus.
As for multinational orgs, our Director is a former assistant Secretary General of the U.N., and we have instructors and advisors who hold or held high positions at the U.N., the World Bank, and the IMF, so there are several "ins" available.
It's a great program, and I hope to see some of you next year!
Good luck with the decisions.
