I've worked with three in my career. At startups they tend to get promoted into upper management, which is a rare sign of justice in the world.

If anyone is in Norway and is good with Java or C# I might be able to get you an interview somewhere that has good managers. Email should be in my profile.

pay > 100k €?

Probably not. I didn't think an engineer here can expect cross 100k€ without either 1.) running his own consulting business well or 2.) having huge performance bonus and perform well or 3.) cross into management or sales.

Do you know many engineers in Norway who earn > 100k €? I was not able to figure out from your profile if you know Norway or not.

I know Norway - was just curious. Your explanation matched my expectations. As most places: Once you hit the ceiling the only way forward is sales.
