Wouldn't that be a red flag if they don't have any public code at all as a senior developer? They aren't fresh out of school or just starting their careers. They should have something.
I'm a senior developer and my github is half guitar tabs. I'm not interested in peacocking. Maybe it's because Hackaday refused to put my name on the article with my senior design project years ago and I just don't want to play the game.
I appreciate it. After thinking about this I think I just need to get over my hangups about duplicating things already done or things that aren't really important.
I just take tabs and rearrange them for personal use. Learn from my mistake and just post whatever to your github, if you fret over its usefulness or purpose you might just never grow your portfolio at all. This was a mistake. You don't have to have some gnu front-page exploratory project.
If you want to shred guitar look up Troy Grady to grok efficient mechanics that won't break your wrist (we type alot for work as well)
Mine too. Or 99.99% of it at least. But if I were to apply for a job, I'd focus more on having at least a little repo of something to show, than on polishing my CV or doing leetcode excercises. That 0.01% code I wrote which is my github is my CV. That 99.99% I wrote for my last employer won't be seen by my next employer.
