It is definitely necessary for me, because I majored in design (graduated this year), and a good cover can reflect my personal aesthetic feeling and skill level.

I am purely professional, but it is generally necessary to make a simple cover. Put your name, contact information, the position you applied for and other simple but necessary information on it, because the interviewer will probably look back after turning over everyone's resume. This cover resume will save the examiner's time and will naturally leave a little impression on you!
