Yes, on paper just in case, pdf(best format to send it to someone because format of text is sure to stay the way you did them and everyone can open pdf) and docx or odt when im editing it. I dont think some multimedia or video CV is good, thats for portfolios in some fields and maybe job application if the job you apply to is on some field where you want to show your video edit skills or just shine naturally on camera, ofc not a good idea to make some wacky video for office work application..

I have one. It's required for just about any academic field. Literally every single person I work with has a CV and updates it at least biannually. It's an electronic document that outlines your education, experience in the lab/field/teaching, publications, professional presentations, and awards or grants that you've been given. Not much different from a resume except that the focus tends to be more holistic and encompasses your entire professional history, as opposed to a resume which tends to be tailored to a specific job.
I don't have one anymore. Well, I probably do but it's at least a few years out of date. After I was licensed, I was pretty much set. Most of my work comes from word of mouth and I've vouched for by references in the world of engineering. It's also not my primary source of income, anymore, as I'm self-employed in other areas as well.
Having read about the "personal branding" movement, I'm likely to chalk it up to hipster irony or something. I don't know; I'm not good with irony. I could see it if the person is a writer or photographer or something artistic who actually puts forth a personal style, but a personally branded engineer or secretary or HR person just sounds ridiculous.
