A while ago, I learned about this neat trick from Harry.
You can write your resume in Markdown and convert them to PDF using Pandoc!
Since Markdown is plain text, you can version control it with git and create branches for whatever company you’re applying to. You can even share the repository with someone you trust, and they can do review the commits on GitHub.
Pandoc uses Latex to render the PDF, so they look very “textbook formal”.
All you have to do is:
pandoc resume.md -s -o resume.pdf
Try it out!
You can do this for all sorts of documents, not just resumes.
