I am a current student at SSE finishing my master's in Accounting. I answered a few questions under a SSE MBA program and ended up accidentally hijacking the post.
If you have any questions about SSE, please read this post. I left a lot of answers there.ask-a-program-advisor-from-stockholm-school-of-economics-113461.html#p1012657
And feel free to ask me anything else. However, I am not an admission officer so I cannot answer anything about the process of admission from their point of view. I can only share my experience.
