Been through it didn’t get a job - moved on with life.
my advice - don’t do it
If you decide to anyway; get some other skills first do something a bit different first get some money behind you.
if you are willing to spend your own money you will probably be able to keep at it.
easyjet et al only recruit newbies from their ATOs if you want to get straight in with them and others that have a similar set up go integrated.
modular etc is fine but never expect to join an airline - yes it might but you should plan to be an instructor and content on being that way for a good portion of your prime years where you would be developing in another career.
