Anti CV (overleaf.com)

I get it, but it's really negative and self-flagellating.

I think it would be both more positive and more useful to identify areas that you know exist and know are valuable, but haven't mastered, yet are working on or intend to work on. Cf. antilibrary.

Thoughts on including emojis in a resume/CV?

I would view that very negatively as a hiring manager.
