From my personal experience in game-dev in Berlin, the highest earning coding individual-contributor (so not a manager) salary I ever saw was 70-something €k per year (and it is quite rare to go above €65k even as a very senior programmer).
You will literally have to be C-level at a large and succesful company to earn €120k+ as far as I can tell (in this sector).
That's my impression as well, of the job market in Berlin as dev contributor in many industries. There exists just rock solid ceiling at 70k EUR and that's it. No idea about stricte managerial roles but these are oftentimes reserved to native Germans and the competition is beyond fierce so forget about it (unless you are Abmahnung, Betriebsrat, and Arbeitsrecht virtuoso).
I was apparently pretty well paid at my last job (Game Dev) at 68k EUR a year.
Also, note that a lot of Europeans quote salary after tax, which can make a big difference.
you're competing with wide-eyed 23 year olds
Not for senior/lead roles (I've done hiring in several companies). There are lots of people competing for junior roles but its still not that easy to recruit true seniors (10+ years work experience).However sometimes there seem to be like parallel realities when it comes to salary.
