Myself, and alot of my friends (that I made during training) went through the EPST training and are all flying RHS of a jet (146, 737, 757 and A320) for different airlines (easyJet, BE, BA, JMC, DutchBird, Go).
Those I know are either still in training or awaiting typerating at the moment. Nobody has been at home for a prolonged period of time, or 'forgotten' about. There have been 2 or 3 dropouts I won't deny, but that was caused by the students themselves, mostly motivational.
All in all EPST has simply delivered what they promised, no b*llsh*t!
