By contrast, you appear less appealing as a result. If all you want to do is show up to the mill and get paid, stop applying at all the most prestigious mills. There's thousands of more humble mills that could use your help outside the valley--and they don't mind if you buy your toilet paper at the store.
You can't pretend that there aren't plenty of non "prestigious" companies that do this. Frankly the fact that any company would judge you based on "oh, you don't spend your unpaid time doing work that we consider important?" is absolute bullshit, no matter the "reputation" of the company.
These jobs are just another cog in the wheel job for christ sake, stop putting companies on a pedestal just because of their name.
Furthermore, if you're applying for a "desirable" role and you don't have any previous experience and NEED to use a github profile to show yourself off, it's clear that the only thing making this role "desirable" is the name on the fuckin company building which, again, is a bullshit reason to consider a job "desirable".
Otherwise, a "desirable" role would be one that could be a senior role in a field that you already have experience in, so your actual work experience should be plenty of evidence for your worthiness for the position and you shouldn't need any outside hobby code to show that you're qualified.
