Thanks for the info dgpu, the academy is definitely reputed in Europe, and you are right about the high EU focus in their curriculum, some students of the academy also told me the same. They also told me the difficulty in getting jobs especially for non EU students. Had it been IHEID or Science Po, I would have considered it for sure, but for DA , I need to research really well since the ETIA course has been offered from last 8-9 years only as compared to the more famous 2 year International Studies course.
But again, considering my engineering backround ( top 20 Uni in India) and above average grades (CGPA: 7.94/10) I think i'll have a slim chance even if I apply next year for ScPo and IHEID. Instead, giving GMAT and applying for an American MBA after some years of work exp makes more long term employment sense, but then I've always been interested in International Relations. Confusing situation for me..
