During the interview they ask you about mandarin skills to know how serious you are about studying in China. Most of the Indians didn't speak Mandarin when they got admission to CEIBS, so this is not exactly a major criteria for admission. It's mandatory to learn Mandarin, after you get admission in CEIBS (School arranges for a pre-course - this optional paid course - and then a subsequent free Mandarin course).
