I chose Indonesia because I got a CLS there last summer. There's no language requirement but I figured I would be more competitive already having a functional grasp of the language. I also didn't exactly fall in love with Indonesia when I went there. I had the worst culture shock of my life. But I also felt learning to navigate the pretty extreme cultural differences made me a better person. There's also very little opportunities to study Indonesian outside of an immersion environment. There aren't good books on it according to my teachers so I'd like to improve my Indonesian.
things I do love: the landscapes, how much people smile there, their sense of humor, their approach to story telling, how concerned they are for others, the juice
things that make it challenging: being treated like an object, photographs, lack of privacy (I have so many stories about that)
But that's not a pros/cons list, the challenges add to why I chose it
