There's the kind that, when given a problem, will jump in, learn what they need to learn to solve the parts they don't fully understand yet, deliver meaningful iterative results, talk to people as needed, keep you posted on their progress, loop in other team members and offer/request help to/from them, take initiative on the obvious missing parts that would benefit the project as a whole, etc.
And then there's the rest.
Within the first few years of someone's career, you can quickly tell which kind they are. It's almost impossible to turn someone from the latter group into the former.
Yes, everything else is a façade. You can be a "senior" developer with 30 years of experience and still be in the latter group. And you can be fresh out of college and be in the former.
Now some people are extremely good at other skills (politics, interpersonal communication, bullshit, whatever you want to call it) and will be able to seem to be in the first group to the people who matter (managers, execs, etc) while actually being in the second group. But then we're not talking about actual software-making skills anymore.
You can also totally be in the first group and be underpaid, never promoted, etc. There's little correlation with actually career success.
This is depressing and seems right. And yet this is something I desperately want to be ignorant of. I don’t want to peel apart my brain for anyone. Working within these kinds of problems is pure pain.
That's incredibly unlikely. Do you need to be an employed surgeon to become a senior (or whatever they call it) surgeon??
I very much doubt you can be senior without having actually spent years doing it professionally. The experience is everything, no book will give you the sort of understanding you need. That's unfortunately human nature, we are not capable to learn and internalize things simply from reading or watching others do it, we absolutely need to do it ourselves to truly learn. Didactic books always have exercises for this reason.
You can learn facts and techniques from books, obviously. But just because you've read a book about Michelin restaurants that you can now be a Michelin Chef.
Picked up a book on XHTML (no, that isn't a typo) and CSS in 2007, just kept trying to build stuff I wanted to build and backfilling knowledge as I went. Not only is it possible, it's preferred. ~20 years in and I've learned how to build my own full-stack JS framework, deployment infra, a CSS framework, and an embedded database to boot.
Not one drop of this would have been possible had I taken the traditional corporate track.
That is, and has always been, true. Currently, however, the narrative that is sold (and unfortunately accepted by so many of the senior developers who post here) is that the experience of telling someone else to do something is just as valuable.
There’s plenty of people in this world who are expert programmers without following any traditional path.
