This rant is not about avoiding bad company but instead: If you find your self in a bad company make sure to note what is bad in terms of:
1. What is wrong?
2. Is it wrong by your book or by everyone's book?
3. How things should be done if you were in charge?
4. Are you able to be productive if those "wrong" things where done correctly? For example if they should have used gitlab cli for auto deployment, do you know how to do that? No? Learn. Yes? Move to the next item in the list

There is no way to avoid bad companies unless you are really lucky, just make the best out of where you are now :)
