It all depends on how you look at it though. I know it's easy for me to say (who is already in the system going to stage 3) but if you compare 6 months to all the years you could be working for NATS, it's really just a drop in the ocean. I know it's terrible to wait (just wait until you're waiting for your stage 1 result!) but looking at the bigger picture it might be worth it.
The best of luck regardless of your decision though
