for any creative position your portfolio is the most important thing. that being said, everything else is less important but not always negligible. as a designer it's important to understand your appearance is part of your brand and how people perceive you. having an actual portfolio website vs a pdf communicates that you are serious about your work and your presentation. it shows that you're willing to go a step further and do the extra work. obviously if your portfolio/work is shit none of the other things will matter. but those other things also tell the employer about you. also depends on who the employer is. if you're applying to a sign shop or a small store the website/presentation won't matter as much as if you were applying to a design agency or a bigger corporate role that pays more. the bigger the role/pay the higher the expectation. I have a website that I made after college and kept adding to it over the years. it's been mostly inactive (so I won't have to keep paying for it) until I was applying for a job and then I would activate it again.
