Hola Topharry,
I also decided apply and go out this rubish country called Spain. I sent the app for FO and in my case It was quick answer but other people says that It takes around a month for recieving the invitation. So if I were you would try to give them a call and see how is your status.
In my case i did the test more than two weeks ago and news Should come soon.
Good luck and good decition to go out Spain there is good company out there.
Kind regards,
S.
