If you are an experienced pilot, I feel an interview and sim check should suffice. However, it's their airline and they make the rules, no matter how wacky.

At GO you are expected to be a full time cheerleader for the company in addition to your flying duties.
Once I'm off the aeroplane I prefer my time to be my own.
