- If you're shooting resumes off into the void of companies "apply now!" pages, it's HIGHLY unusual for them to be looked at by a human. And when they are, they'll probably be considering more data points (looking at your LinkedIn and GitHub). So here it's best to make them "machine readable, human-tolerable".
- If you're handing out resumes at an event, you are going to want to make it terse and punchy. Sell your impact and skills. I think this is the least degenerate form of resume. Also, I've never done this outside of my career fair in college, where your resume is basically just your GPA and expected graduation year.
- If you're being referred, your resume is mostly for talking points when you're chatting with someone. So making it like a powerpoint is best for this.
Plus, for the first one, most of the time you just get ghosted. So forget overly tailoring your resume to the company, unless it's one you really really want into. In which case you're probably better off poking around and trying to either find a recruiter or find a referral even if it's just a "I talked to this person once and they didn't punch me in the face at all, you should interview them" referral.
I'm honestly kind of passionate about resumes, in theory? "Here is a 1-pager of my professional career" is an interesting problem. Unfortunately, that's typically not the problem you actually need to solve when you're sitting down at your doc titled "Resume".
