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.

tl;dr at the bottom

This might not be a popular opinion, so please, if you throw things at me, limit yourselves only to tomatoes and other soft projectiles. Thank you!

So this being said, i must say ut: i actually like how facebook use this data overall. While i am completly against privacy violation, that data is given up by ourselves with a choice to do it, so we can't hand them for it. However, i think the fact that we got ads for what our interests are is quite awesome! For example because of this i found webcomics and artists i curently hold really high in my praises and this might not have been the case if FB had another business model.

This being said, i just think people should focus on problems more important than how social media manages to earn some bucks, and while is our choise to be part of that we can't simply call ourselves "products". History holds many stories about civilization that gaved no choice if you wanted or not to be a product so we could be at least glad it is not the case anymore.

Anyway, if you read all the way down here, tnaks for your time!

TL;DR: Facebook is no holy church but it actually not so bad, we can find things we get to love or actually needed in the first place in their targeted adds system. At least we have a choice to be part of this or not!

Started a new job last week. Pays a tad below average for position, but i get training time and budget for anything i want.
So far i have had few days of company introduction, and now a week for training courses related to position.
I have not seen any code yet, brought no value in, just joined.
Massive green flag to me.

Not leaning on unit tests. I usually write them after testing my code manually, and lose time for testing feature by hand.

Company i work for just posted updated pay rates.
It's good. They went from lower end of spectrum to a little above the average in terms of pay, and benefits stay the same - solid.

Why the hell does that happen?

I spent ~12h working on a simple issue/bug.
7h was spent on rebuilding local dev environment which is a clusterfuck of maven profiles, tomcat, some autogenerated degeneracy, and 2 different build systems for JS.
5h spent on actual bug fixing, code reviews and so on.

Get to know the new company better (Changed job shortly before Christmas).
Learn some DPs, DDD, k8s, finish introduction to hacking course, start doing htb and thm machines, finish and defend my thesis, finish books clean code, thinking in java (reading it to fill in gaps on knowledge), a few books about pentesting.
Among non tech goals: pass drivers license exam for cars, another one for motorcycles, go back to learning russian.

Got pissed that my story delayed the whole project by 3 weeks (major story, lots of changes, and management decided to put me in a few extra activities outside of the project).
Stayed up until like 23:00 to deliver PR.

Update of previous post
I just got assigned to a project.
Project-specific training is designed to take up to 20 days.
I got materials, videos, and a person who is in this project for a long time to supervise training and introduce me to the project.
Only problem is that the project apparently uses 5 years old version of base framework.
