There are many interview counseling classes, but not many authoritative ones. I know which is better: Dagong, Zhonggong and Tuhua. Tu Hua has little to do with them. I feel that the teacher is very ordinary when I attend classes in Zhonggong. My classmate's written test is lower than mine. His interview score in Dagong class was very high, and everyone passed. Hey. . I can only fight again! Personal opinion, for reference only! Good luck!
