End of camp commissioning; how does it work?

I'm gonna try and keep it short and sweet, kinda like my love life.

MS4 here who recently contracted (I know, don't ask) and am graduating in the spring. I'm told that I'm going to be an EOCC but I still have to do my tab and branch interviews. I was also told that because of my situation, I would do my interviews during CST next summer (assuming there will be one). Does anyone have any insight on this as far as what to expect, how my accessions and interviewing would work, when I would expect to find my total OMS, component, and branch? I feel like I'm looking for a needle in a haystack in pitch black when it comes to finding answers. Much obliged.
