What time should I arrive to find a job outside and go to the talent market? What do you need? Are there people recruiting there every day?

Every talent market has specific opening hours, so ask before you go. Then you'd better go early, because some companies will recruit outside the venue. And relatively more likely to go early, and then print out your resume in advance. It is estimated that 5- 10 copies will be enough. Don't send out resumes.
