The same is valid for Munich. 2-3 bedrooms plus dining room is <2k here. However it’s not the best apartment in the city, rather okayish. Also it’s hard to hit 5k after taxes salary limit here.
It is absolutely possible to get more than 5k after taxes as base salary in Munich as a true senior software engineer. Lots of what TFA calls "tier 3" companies are in Munich.
Could you please share some information regarding these companies? I know one - Apple. But 5k is not their base salary, it’s lower with ton of stocks on top.
Google is hiring in Munich too. I couldn't find public salary information on salaries there though. I'd say it's competitive enough that I'd be willing to relocate from London there.
