In Germany this isn't a thing, but when applying for a few jobs in the UK most employers considered me senior after that interview. Still didn't get the jobs, because I failed their programming tests.

Since I started programming my work-behaviour changed from asking people all the time when I don't know what's happening to reading their code.

I think developers are considered senior if they can work on their own.

Like, if you get all the engineering practices of designing, implementing and maintenance done without much help.
