This question should be a personal hobby, not necessarily only one, but also depends on the boss's preference. Some companies may think that you have only one resume and nothing. If you don't pay attention to this job, you won't have a good impression on you, and some companies will come up with a resume to show that you are very capable, do things neatly and meet the boss's taste. Therefore, it is recommended to prepare more resumes in case of emergency! ! !
