A4 plain paper will do, no cover. Many people make their resumes colorful and complicated. They look beautiful on the surface, but they are really annoying.

When I (I am a HR teacher) receive my resume, I will think that those who have beautifully bound it are naive, grandstanding and don't like it.

So I suggest using ordinary A4 white paper, 1 page, no more than 2 pages at most.

I wish you success. You can email me if you don't understand anything.
