This one is total fail. About the only qualification you need to get in is to be the son or other close relative of an employee. I'm not exaggerating, the jobs are effectively hereditary.

I hope I can get in on one, they seem really fun.

I think I've just found my new vocation :) The news did an assessment of salaries recently. Municipal workers and bus drivers were right at the top (and it's impossible to get official information for those; they'd put together lots of different sources), and at the bottom, teachers and specialist doctors working in public schools and hospitals. A bus driver earned about three times as much as a doctor. And guess who goes on strike all the time? the bus drivers.
