Write it in Markdown and let Pandoc turn it into LaTeX or whatever you desire

Uhhh..probably you and .2% of hiring managers. I've never cared when hiring, and have never heard this advice anywhere but this post. No offense, but if it was as common as 10%, recruiters and bloggers would be suggesting it left and right.

10% is being exceptionally generous I think. Anecdotally I've never heard of a single manager getting a crap how your PDF was produced, and a lot of the hiring and recruiting agencies will probably end up snapping the data out of your PDF and converting it to some standardized format, so the Latex will be completely rendered out.

To me this feels like a case of a publisher passing on a novel because the author wrote it using notepad.exe versus vim.

The font will be Computer Modern, that's the most obvious one.

Perfectly aligned paragraphs on the left and the right. Other packages produce ragged line ends and/or ridiculous spacing between words (Word’s justify)
