Haha I remember for my first dev job thinking the hiring manager would watch a ten minute long tech demo I’d posted on YouTube of my personal project. I was so excited when I interviewed and asked if he had watched it, he responded with “I glanced at it”. Ten years year and having hired people, I laugh when I think of that interaction.

That said, if someone applying to a Junior dev position linked me to a YouTube video in their cover letter explaining a personal project they’d been working on, it’d for sure put them at the top of the Junior dev pile for interviews for me. So I guess maybe it did help, as I did end up getting the job.
