A Question about Resume Template

Must be have to add Cover letter to my resume template?

I don’t think it’s required, but I think buyers would definitely appreciate having one with it.

Without this, it seems that it can’t pass the audit.

As in your resume template got rejected?

To be honest, that could be an item quality thing, and not the lack of a cover letter.

i have always been wandering as well , a lot of guys provide it with but not sure this is required too
