I applied for the Sharp Cadetship back around 2011-2012.... got rejected, applied again in 2015, got in... just keep at it.. perseverance.... When I got rejected all I did was go back to work and sorted myself financially in the meantime, then when mining slowed down thought I would have another go... I am much better for it from a financial perspective in the fact I have my car I own outright, and a house... so now I can ENJOY the flying - even if I don't get paid as much in flying - as long as it covers the bills I will be happy. :-)
Also a tip for applicants, I know mining companies actually use software to scan CV's, and the software picks out the CV's to show to the HR Recruitment.... it scans for Keywords that they choose.... like "SAFETY", "LEADERSHIP", "SOP" etc. ...not sure if Virgin use such software - but it wouldn't surprise me.
