Rave: I have a tentative job offer. If I can get a security clearance then I will be employed beginning in July or August.
Rant: I realized I did have an issue that could affect my ability to receive a security clearance. Although I have been advised it most likely won't hurt my chances, I don't have all the facts related to the issue and need to obtain the information. I have cancelled four interviews after receiving this offer, and I will be very angry if I cancelled them and then get my offer revoked over the clearance issue. I was told to cancel them because I would have to respond to them before I could find out what happens with the security clearance issue, and my signing of the tentative offer obligates me to be employed there if I receive the final offer.
Rant: Worrying about the security clearance issue has pretty much dampened any excitement that I have about getting an offer. I really wanted to be excited, but I fear that there will be no excitement felt for another month or so. Then I'll probably just be feeling relieved rather than excited.
