I have a mate who got Norwegian last year via Kura, they have sent 22 candidates and 20 got offers, CTC sent 20 and only 6 passed, that says a lot. I had the opportunity to visit them and watched a assessment prep day(it's a week long) and I am very convinced by their methods.
From the conversations I had with their trainees, those who didn't get placed were either unlucky or failed the technical part. That said, they were given opportunities to apply where its usually reserved to CTC/OAA/FTE. I am still thinking what to do but possibly will join then as CTC screwed me over.
