NAI doesn't hire pilots. That's the point. The Singapore staffing agency hires pilots. You'd have to interview with them. Then they negotiate a deal for compensation with NAI. Which means even less money for you. If they are paying them less than what they would pay for pilots, Singapore Pilot Co would still need a substantial cut to run the company. That's even less wages for you the FO. But in reality, they wouldn't hire you because they'd rather fill that seat with a guy who is fresh out of flight school and willing to work for zero dollars to get flight time.
