I've been at big companies for 12 out of the last 20 years, never a FAANG, just "average" big companies. The rest of the time I've spent at startups and medium-sized companies, and sometimes a startup-in-a-big-company.

I have met maybe 5 good engineers in my whole career. The size of the company did not matter. The reason is, the only thing that exists in our world today that can make you a good tech engineer, is yourself.

When you hear the word "engineer", you might imagine a professional who has done studies, passed exams, has certificates, maybe even apprenticed. They know a specific body of knowledge (which is maintained by some organization), they're held liable for their work. They are masters of their domain and they don't step outside of it.

But not if they're in tech! Then an 'engineer' can be a high school graduate or a PhD. Both can make the same amount of money, and have the same lack of real-world experience and job skills. They will both regularly apply technology they've never been trained on, never learning more than the least possible information to get a proof of concept working (and then that immediately becomes a production service). There's often no record of the decisions they made, no formal design process, no architectural review, no standards listed, no testing required, no risk analysis performed, no security/safety/reliability checklist performed. And they often are dealing directly with PII, with absolutely no thought to how to manage it. And they often have far more access than they should have, leak critical credentials everywhere, don't manage the software supply chain properly, don't even pin versions or even test rollbacks, etc. I have seen all of this at every single company I've worked for.

In any other 'engineering' profession, this would be illegal. Hell, it's sometimes illegal just to change a breaker in a subpanel in your home without pulling a permit, because doing it wrong has consequences. Think of all the times your personal financial records, health records, sensitive data, social security numbers, etc, have been leaked, just in the last year or two. 9 times out of 10 those happened because nobody cared enough to prevent it. But these things shouldn't be optional. There should be some kind of mandatory thing in place to force people to ensure this doesn't happen. And some kind of mandatory minimum requirements about what people know, what they're allowed to work with, and how. None of that applies in tech, yet we still call it engineering.
