Profiling is much more criminal justice and criminology (i.e.., MOs, criminal patterns, recidivism, and statistics) than it is psychology. Forensic psychology is really something else entirely. I think the big-name profilers have actually been career law enforcement/FBI agents, rather than psychologists of any sort. I always assumed that a profiler would be seriously handicapped if they had never actually "walked a beat" or at least spent time in the trenches as a detective working in law enforcement and/or criminal investigations.
Not to insult profiling or anything, and I realize that understanding the mind/drive and motives of a suspect are important, but narrowing down a pool of suspects based on data and assumptions with relatively poor sensitivity and specificity seems quite dubious to me. I guess I've just never really "got it" or understood what all the hype was about. Maybe you can clarify any misunderstandings I have?
I would also make sure you have other viable, perhaps more realistic, career options. The Behavioral Sciences unit is pretty darn small, no? How many people are actually employed there? 20? 30? Given how small it is, as well as your peer competition, what is the likelihood that you could gain employment there? Its possible I'm sure, but you have to admit that statistically, the odds are against you. In fact, employment with the FBI in general is a very competitive and arduous process. I buddy of mine from high school started the process in 2007 and didn't actually start working for them until late 2009 due to the intense personal investigations and background clearances/checks. All I'm saying is just make sure you have a flexible and pragmatic career path.
