I wrote my CV with org mode, thinking this would make it easier to refresh it by simply adding new refs to my bibliography file, but it's not as smooth as I expected.

I tried org-ref, but I hardly can make it work again any time I need it.
Now I'm trying with basic latex, and I still can't make it work correctly. (I've heard about the new citation system but it's not released yet and I'm really not trying to experiment a lot of things and change my whole completing-read backend right now)

I am down to this situation: at the end of my org file I specify the bibliography file, style, and nocite everything with a * (because I really don't want to manually add every ref, that's the whole point)

\nocite{*} \bibliography{biblio} \bibliographystyle{plain} 

This nearly works, as it inserts a bibliography at the end of my CV, but the citations are in the order of the bibtex file, which would not be a problem if zotero did not completely randomize those refs.
Maybe someone here does know how to get zotero to export in a set order, or org/latex to cite in a set order?

Also, bibliographystyle{…} seems to be completely ignored as it's always the same citation style no matter what I write between the curly braces. Do I need to use a package even for the basic citation styles?

My org-latex-pdf-process (of which I have found countless different versions on the web…) is '("latexmk -pdflatex='lualatex -shell-escape -interaction nonstopmode' -pdf -f %f"), maybe it's not the right one? (previously I had one that circulates with 4 entries in the list, it's not getting me better results)

I'm on archlinux with texlive-core, texlive-bin, texlive-latexextra, texlive-bibextra, and bibtool installed. Org is 9.4.6. Emacs is 27.2. Do I miss latex packages maybe?

This seems to be mostly a zotero/bibtex/latex question, but I'm pretty sure I'm not the only one trying to write my CV with Org so these must be not so rare concerns (although I cannot find good ressources on the net about these!).

Thanks for the help!

edit: I tried using bibtool to sort my .bib file and be done with that part, but bibtool can't even sort by the date field (ISO encoded YYYY-MM-DD) correctly! This is insane.
