What types of trainees fail during the agent recruitment stage?
A trainee will typically fail during the phase of the training that deals with recruiting if the CIA instructor, who's usually a seasoned CIA officer, feels that that person lacks the skills that are necessary in order to recruit someone. It could be something as nebulous as basic social skills, but it could also be an indication that you as a person are not likeable, an indication that you're not going to be ethical, an indication that maybe you would let your own arrogance or egoism get in the way of doing your job. Your job is to make the foreign agent feel like he or she is the important person, and to devote yourself to that relationship. If you show signs during training that you're not going to be an effective spy and you're not going to be able to recruit someone and the instructor feels like, "I wouldn't spy for this person. I wouldn't commit treason for this person. I wouldn't feel that this person had my best interests at heart or that this person was going to take care of me, to make sure that I was never exposed", then you're not going to pass that aspect of the training and you'll get cut from the program.
