Their test is to translate Chinese into English, and what they do is patent translation.
Before taking the exam, it is best to search the basic terms of patent translation on the Internet, such as "Invention discloses a water pump". The word "public" here can't be published, only the claim can be published, that is, the invention's claim to the water pump. ....
Anyway, you'd better practice your translation speed before you go, because the test draft of that company is a bit long (for those who are new to patent translation), and it usually takes you 1-2 hours to translate the title, abstract and patent claim.
I wish you success!
