No . . . I don’t think that they will not have a position for you. Although that does happen. In this business, contracts, funding and needs can shift quickly. They might be in a position where they really don’t need you until December. If that’s the case, they might try to push your start date to November. I’m not trying to scare you. I’m just trying to explain why we can’t answer your question.
You asked how quickly they will bring you in.
The reason that I suggested that you explore the market is that you now have a valuable commodity. A current clearance. This means that another company could start you next week if they have a need.
