Should answer your questions
Dr. Pie,
I believe you have to wait 12 months between the dates of your initial applications - so if you first sent in your previous application before Jan 30th last year then you can now apply again. I don't know how efficient NATS are at picking these things up, but seeing as you are trying to apply for a job with them I'd suggest dishonesty is not a very good idea so I'd recommend waiting until you're sure the 12 months is up rather than trying to sneak around it.
