I reached out to Miburo with interest in their China analyst posting. They were looking for a Mandarin speaker with China experience. I am fluent in Mandarin, lived in China for years, and have used Chinese regularly for my past work. Miburo then gave me their 'test' which was: 1. In Cantonese 2. In entirely traditional Chinese 3. Was about Hong Kong, not China 4. Had no frame of reference for grading, just "tell me what you know about x website" I never got a call back, but soon got a better job doing actual Mandarin China analysis. No clue what these guys are actually looking for..
