Pass the customs first, then pay the money, that is, if you pass the exam, then pay the money. I haven't participated in the written training, but I have participated in the interview (everyone around me has participated) and paid more than 10000. At that time, it was said that if I passed the interview, the money would not be refunded, and if I failed, I could get some points back (estimated at 34 thousand). The content mainly talks about some interview skills, and the interview questions are = =. As a result, the interview content was not deducted, and dozens of courses were practiced for nothing.

I hope it helps you, and I wish you success in the exam.
