Unless you're currently in a-pool, there's not much point in asking about current wait times. Whatever it is now, it'll probably be different by the time you arrive. Wait times are generally longest in late summer when academy and ROTC spring grads arrive. Also in mid-winter when the December grads start checking in. But worst case, you're looking at a few months collecting a handsome paycheck and maybe given busywork. Generally the odds of getting a good stash job are not in your favor, but if you're given one, don't screw it up.
