Thorbjoern, nice to see a Norwegian on Rotorheads, welcome!
Given the size of Oslo's Police Air Unit I would think it unlikely that there would be many in a position to respond to your query. For now I would simply say .. do your best and, with that, to wish you good luck.
Presumably in the advert they gave some indication of their requirements and, if you meet those, then you are off to a good start.
