In my experience, admittedly not that long term yet, no one even looks at repositories. I got really good stuff in there, that demonstrates my developer skills, but hiring people never seemed to even have taken a look, nor shown any interest in what I might be able to present to them. Instead they me gave BS ad-hoc coding tasks in the interviews. Could also be, that they are unfamiliar with any of the not mainstream stuff I did and did not dare ask questions, because they felt out of their own depth.
