2) There are not many handwritten documents, and most of them are sorting out various materials, such as lawyers' work records, case materials and unit files. Most of these are electronic versions needed for machine typing. Don't doodle. This is a question of attitude.
3) Law firms have no age limit for assistants. It takes years to treat you as coolies. Why do you take the civil service exam now? This has nothing to do with your job.
4) The salary depends on your local habits. Some areas are different, but some are not even enough, and some are free. But overall, the salary is very low, and it is very likely to ask for family support. You should be prepared for hardship.
This is a necessary stage for every lawyer. I hope you can get through it smoothly and become an excellent lawyer O(∩_∩)O~
