Just bring a resume to the job fair. It's best to write as many advantages as possible, and it's best to write something that people can see at a glance, because people won't spend more than three minutes on your resume at job fairs. Only write advantages, but the job fair mainly looks at experience and education, and rarely looks at others.

If you pass the first level of the job fair, you will be informed of the interview, and then you can bring another resume.

Resume includes cover (black and white, depending on the individual), cover letter, resume, diploma, degree certificate and other related supporting materials. Order as many as you have.
