I think the 300 hr pilot still has opportunity but the competition is going to be stiff in the months and years to come.
Indian national Captain's are being allowed to fly on their FAA licenses for 2 years and have to convert by the end of that time.
Those completing training in the next 6 months still have a shot, the rest will have to take their chances with perhaps being unemployed for a while.
The shortage is for qualified Captains and not new F/O's.
