Go With the Clearance and the Training
The most valuable advice I can give you is to accept the offer that comes first and provides you a Top Secret Clearance and, ideally, promises a training pipeline that aligns with your objectives.
While most want to work for CIA because they know the name so well, they do not realize that better training might exist elsewhere. For example, if you can get a clearance and intelligence training faster from DIA, then why not take it? Most agencies perform the same training these days and your skills will translate directly to other organizations, should you want to switch at some point.
Bottom line, you cannot truly understand and evaluate the different components of the intelligence community until you are in the intelligence community. So apply often, and get inside.
