Probability of booking Financial Management & Comptroller job

Hi there, forgive me if this has already been asked.

My background is in accounting and I am about 4 semesters away from finishing. I mentioned to my recruiter that while I am understanding that the AF will put me where I’m most needed… I really want the position listed in the header.

Is the probability high that most don’t get that position? Let’s say based on a high as a score… would something set me apart or is it really a gamble?

Thanks in advance
