Why ?
Why would Virgin be recruiting cadets ?
They've made huge losses for the past 5 years and only just recovering ?
Plus their new aircraft (789) are replacing their ageing 343/346/744 as they don't want to pay for expensive D checks.. No fleet expansion. So where is the big demand for new pilots coming from?
And they've streamlined their operation to get away with 2 crew operation to a lot east coast and Caribbean destinations (almost 33%) of their route network.
I'd be very surprised if they took on cadets unless they're looking for a few skivvies to do general ops for a few years before slotting them in when there is natural decay.
