I am a current turbine jump pilot, BPA Examiner as well as the normal flying day job.
We look for people who are experienced pilots and not hours builders. The problem with hours builders is they are always looking for an exit and it has to be remembered that it costs us around £15k to train a jump pilot so we want a long term commitment.
As has been pointed out it also helps if you are a jumper so you understand how the spot works, the run in and accounting for drift. It is also very true that jumpers are slow to warm to pilots and if you get it wrong you never hear the end of it. Also at a lot of DZ's if you get it wrong you can do some serious damage to people and property.
Jump flying requires precision and excellent handling skills. In a twin turbine you wil be flying a fully loaded aircraft often at the edge of the envelope and this requires you to be very switched on with the handling characteristics.
Iin big organisations like ours a real understanding of the economics of operating turbine aircraft. Speed and good handling is off the essence coupled with absolute attention to safety. We do 15,000ft and back in 11mins so you are doing 5 TO/LDG an hour and we will fly max hours in a day when it is busy. On big events we can be running 5 or more aircraft often in formation.
It is one of the most rewarding jobs in flying when you get good at it but it is not for the faint hearted or lazy!!
