The questions are nothing about your interests or reasons for joining
That was the strangest part of the whole thing for me. I went through the whole proces and wasn't asked once to explain why I had applied. In any normal job interview it's the first question....
I'm sure NATS have their reasons for running the process and interviewing the way they do but it comes across as slightly arrogant IMO. They are lucky it's such a sought-after career. If they had to compete for candidates like other industires they would have to change their approach.
