If a company doesn't have their shit together enough to coordinate an interview schedule and get the right people into the right room at the right time with my resume in their hands, ideally in their hands ahead of time, I don't want to work there. It's a basic competence test.
Lol. I do bring my own resume with me at interviews, but I've never been in the need for that. If they don't have one, they usually have me that can narrate it. Otherwise they should have done their homework.
One reason bringing your resume is a good idea is because scumbag recruiters sometimes modify your resume, inserting the right keywords to get you the interview in the first place.
Unfortunately and apparently some recruiters have interns to convert those PDF's into their shitty doc-template. It happened to me a few times. Every time I had my CV ready and this seemed to help. Knowing LaTeX reflects very positively on you in some circles.
Most people don't have to luxury of going to interviews simply to test a companies competence. They're going because they really want/need that job, and want to make it as easy as possible for the company to hire them.
Bring it anyways. If they need it, you can still count it against them, while not hurting your own chances if the job ends up being worthwhile despite failing this test.
