I am not quite sure what that EDT implies!
Just because it is also a "Norwegian" company, does not mean that it is good!
You don't mention prices in this post, I would think spending a lot of money on a ATR would be wasted money!
What do you think your pay will be there, even if against all odds they offer you a contract after? (why should they offer you, there is another one waiting to take your place after) - and than, where do you go with an ATR rating?
Go and pay for another rating? It will never end!
