What is the written recruitment test for teaching assistant book editors?

That depends on what kind of editor you are. Anyway, editing is a boring job, and you have to test your writing ability, that is, to find out the typos in an article for you. Haha, in addition, if you are a science editor, you should take some related knowledge tests. Liberal arts is the knowledge of liberal arts, and general questions are not difficult. Don't worry, good luck!
