FCIP is more of a hiring mechanism than it is an actual formal program. Every department can use and every department does it different. Some repackage the FCIP hiring mechanism as a new program. Others use it to hire 3-4 at a time and often only have a small note on their web page. Personally, I wouldn't spend a lot of time seeking out a bunch of departments and trying to get the ball rounding.
I put various recruitment programs in the resources tab in GovLoop under recruitment programs. A lot of the programs can be hard to find but very good. I particularly recommend the various acquisition intern programs these days. And if you can learn the tricks to USAJOBS, it can be effective (look for multiple positions, open 3-4 weeks, find right grade and series).
