Ask questions during interview.
Ask about trainings - it's usually a good sign when company offers training budget. Ask about specifics - sometimes it's a shared pluralsight account, and nothing else, which means that that had an idea and half assed it into existence.
Ask tech recruiter about overtime, a good sign is when they have no idea or say that it must be budgeted and scheduled - it means that it does not happen often.
Ask if it is possible to select and change projects, and how often it happens - if often, it may be bad low level management, or people learning new things and jumping between projects.
Also make sure to ask about rules for promotions and pay rises. Good company wił have a clear set of rules in place.
All of the above apply to mid to large companies.
For small company, i'm sure it will be different.

Don't buy the "We're bleeding edge, agile and embrace devops.". Those who proclaim that the loudest are the ones that think they do, but don't.

Oh, and any place that refers to employees as "tech ninjas" or "superstars" or anything cringy like that. Stay away.

This was more how to avoid shitty places. So to find a good place to work, use this statement in your search:

if (!<this_rant>)
{
... // maybe you're lucky
}

I don’t have a real way to find a good company.
As a rule of thumb I avoid startups.

This doesn’t mean all new young tech companies are bad. I avoid the startup rethorics. Those are 🚩 for both new and old companies.

And I avoid crypto, nft and other scam businesses. There’s an high chance that the owners will run away with the money and leave you without a job.

Throu friends,
But you later realize that there is no good companies

There is no good company. There is only your skill and how much you improve it.

@zlice I am going to ...subtweet you? (Screenshot included)

Basically, so much what you said. 100%.

You stumble your way around different companies until you find something that sits right with you.

There are so many contributing factors to the "good company" and as many definitions as everyone will value different aspects of work. Good management? Tech stack to your liking? Kick ass colleagues? Interesting product? Good work life balance? Company contributing to world's welfare?

I can go on. Each of you will decide what is good, good enough, or decent and what sacrifices and tradeoffs are acceptable.
