Hi darkroomsource
To answer your question, there were a couple of guys posting using the names EpsilonVaz and Kangadee who both did 150 hr P2F schemes with EZY back in 2009 who were both eventually employed full time by EZY after completing a couple of Summer contracts.
A long time ago and the EZY P2F scheme is no longer available but it seemed to work for them and if you’re interested in anyone who has ever made a success of P2F then they would be examples.
Not that I condone the practice of P2F but it obviously has worked for some individuals in the past.
