That's definitely the kind of salary you'd be looking at after an undergraduate tech degree in Austria or secondary cities in Germany.

Can confirm, and there are worse offers prevalent than this. However, that's industry average, I don't know about the specific companies in question.

it's definitely not industry average

at least for jobs which often are referred to as engineers (through legally speaking are not as enginer is a protected title having little to do with software development)

maybe for jobs of people which mainly idk. replace hardware in servers all day but don't really administrate the servers at all
