A few positions could be posted on nav.no (government social security firm), but it’s not really worth checking.

For language, if you’re serious, I’d probably find a Discord channel for people wanting to learn. It’s literally how I met the missus.
We all learn differently, but finding someone with a shared hobby that you can talk to while doing said hobby is effective. We had gaming in common.

Best of luck to you, and let me know if you have any questions.

And: it’s not utopia here. We have issues as well. Just make sure you remove any rose tinted glasses before comitting countless hours.
