As an older, experienced developer, this is honestly just a sign of a changing shift in the nature of software companies, and, like it or not, if you want to survive you have to adapt.
I started in software over 10 years ago. At that time all of the exciting jobs where for small startups and the best way to get hired was to have a great github profile or some cool projects to show off.
But small startups need a hand full of really talented devs who can solve a variety of problems, and quickly get up to speed on new domains and tech stacks. A few good developers could make a company. So hiring focused on individuals who stood out and had something unique they could bring to the team.
But FAANG companies want to hire engineers that they can treat as replaceable parts. The "rockstar" talent that was required a decade ago is a liability. This may sound like a critique but it makes perfect sense from the business standpoint, and while you can protest this all you want it won't change a landscape dominated by large software giants to one fill with disrupting startups.
It's just a different world and if you want to show that your "experienced" and not just "old" you need to show that you can adapt just as well as a decade ago. I had a moment of enlightenment when waxing nostalgic about github profiles to a really talented new engineer doing prestigious work in deep learning. I told them how much better profiles based interviews where and they reacted with horror. "How am I supposed to build a profile when I'm so busy with school, interning on the side and studying for interviews!?"
Software used to be dominated by passionate hackers, and now it's one increasingly of skilled professionals. The best work people just as hard but in a very different way.
Like it or not, software is not like it was a decade a go, and if you still want to be seen as a top tier engineer you're going to have to do it by the standard of today.
