do you have to completely finish the security investigation and interview before you start the academy? I have not yet been contacted for the security interview after getting my TOL in march. my hr rep told me they just need an 'initial' security clearance and then the in-depth one is 'ongoing'. just curious if that is going to affect when i am offered a class... if they have to wait until the interview is over then it could be a long time! also, does everyone have to do the interview or just people they have questions about? thanks.
