Hi there,
If you are thinking about it... better do it asap. There is a big need for IR pilot (as i hear) in the NS at the moment. Rumour has it( and remember it is a rumours network) that CHC Norway needs 70-80 pilots in the next two years if you fancy a chancge in senery. The IR wont get you a job but it would give you an interview for sure.........then as mentioned before it is a case of "do you fit in the picture" thing...
Total hours is not a problem, i personaly know 3 guys that got jobs last year with 250, 330, and 350 hours total....
Good luck
