My advice is that any company that asks you to pay for initial selection is a good sign that that company needs to be avoided.
The global market for experienced Pilots is on the upturn just now in my opinion. (That situation could of course well turn the other way in a very short time)
I never have, and never will pay an airline for the privilege of an inteview with me - nor also will I pay for any training that I may need to fly their aircraft type.
