6 months is about right for a CTL.
6 weeks ground training
8 weeks sims (fyi there are 15 sim sessions to get through...yes 15!
8-10 weeks line training (100-150hrs to get through)
its a very long process hence the current backlog.
to answer the above question - 300/400 positions are generally at random but recruitment will be for both types.
