I have been working in tech for 18 years, as both an IC and a hiring manager. I do not believe it to be inaccurate. It's how I do hiring in my current role.
I also do not have a degree. In my current role, I was hired on the spot leaving the conference room after my interview. In my role before that, I had three video conference interviews and a take home project.
> I do somewhat agree with this. However, your portfolio need not be open-source work, it's just common as there's some proof (version control, although not tamper-proof) indicating you did the work you're claiming you've done.
I used to be an sysadmin|linux|network|infrastructure engineer. Now I'm in security architecture. What work would you have someone like me show that I did the work I claimed to be doing other than me explaining to you what I did and how I did it? No Github repo is going to be able to properly illustrate the work I've done, or the breadth and depth of my knowledge and understanding.
Public repos are a poor signal. Just my two cents. You want to figure out how people think, that's what an interview is for.
