Earlier quoted context omitted.
I haven't had that experience for a single job that I ever applied to. Always sent in PDFs without any issues.
Recruiters and large firms tend to ask for a Word file. I sent the plaintext file (minimal markdown) I used to generate the pdf to a recruiter recently. They directly asked for a docx instead.
Again, not my experience at all.
I think if a company didn't accept my PDF CV and asked for a Word file instead, I'd strongly reconsider whether I'm actually interested in working there.
