NATS interview process

Stage 3

Hi guys, I have recently found this forum and there have been some helpful posts, thanks!

I've passed stage 2 and got my stage 3 interview in Feb.
On the email it says 'competency based interview' but on a document I found on the NATS site it says there is also a group exercise. Is there anyone who has recently done stage 3 who can tell me what is involved in stage 3? That document might be out of date, but wanted to check.

Also, 8am - 4pm seems a long time for interviews, so I assume there is quite a bit of waiting around?

Thanks!
