I had my Stage 3 in Bournemouth on 22nd April and one of the chaps interviewing explicitly said not to discuss what we had been asked in the interview. I think if you read back over the forum and the NATS Stage 3 PDF document you get a fair idea as what to type of questions asked. What I will say is that it is quite intense and they ask lots of questions about your examples!
Still waiting for the result!
