It depends on what company you are in. Big companies still attach great importance to the surface. You'd better make a cover and book cover or something. If it is a small company, you must first understand its corporate environment, history and so on. Generally speaking, I like this small company, which is just a resume. Sometimes I go without my resume. In some companies, you have to fill out your resume if you bring someone else.

In addition to your resume, it is very useful for you to bring copies of your degree certificate and certificates obtained at school.
