Regardless of the reasons why they are recruiting, it is still a very good opportunity. Beats the hell out of flying bugsmashers. multi crew environment, airline operations exposure.
If you take on this opportunity, then good luck to you. But please don't come running to Pprune after six months and whinge about poor terms and conditions, low pay, poor safety record of this airline and so on. You know exactly what you're getting in to. Merpati is a government airline and one of the lowest paying airlines in the country. It's poor safety record speaks for itself.
And what's the bet some guys will even use Merpati's poor safety record as an excuse to break the 3 year bond when they find greener pastures back home? It's happened before (with SQ in the early 90's when they hired GA pilots from Aus, Canada and the UK) and I'm sure it will happen again.
