All the information I have received is from fellow pilots that I know who have completed 500 hours with Lion Air through Eaglejet or CFA and are either now employed with them or have been employed with them and moved on to find employment with other, larger carriers.
They have told me that there is a delay of one to two months when they arrive there due to paperwork and bureaucracy etc. which can be frustrating. The feedback I have been given is that the organisation isn't great but they did say though that when you start flying you really do build up hours quickly which is why you're out there in the first place.
In two years they have been able to unfreeze their licenses and move on. They all went through the FO program.
