Pros
It's a stable job, which can last for decades for low level ICs, unless they get too unlucky with the manager.
Cons
Unless you come from a good family or have special relations with good people, you will never be treated as a human. Career-wise, the limit would be mid-management — still with very little authority. But with right connections (or manage to represent a minority once a quota shortage comes up), very quick advancement is possible. HR is very professional in finding ways of using protective Norwegian labour regulations for destructive personal abuse for undesirable people. And the pay will, officially, never be high: it's the strategy. The employees should "feel lucky" (a quote) because of relatively better pension terms and discounts in local restaurants.
