Hi there!
Hostee, do not stress about virgin not having rung you yet. i have just landed a place in an august ground school and i had heard nothing for weeks. i had my initial VBRD on the 31st of May, where i informed the recruiter that i would need 4 weeks notice to leave my current employer. Two weeks after my VBRD i got an email saying that they were still processing my application. then about four days after that my references were contacted, then about another week and a half before i got the call for my medical.
So depending on how much notice you told them you need, they may be holding back to maybe put you through to a later ground school, to allow you enough notice to where you work now.
Anywho hope this helps you out!
Good luck and i hope you hear soon
