Workflow is going to be radically different from one LTC pharmacy to another so it is hard to generalize. Some have dedicated pharmacists to handle specific functions and others go for a generalist approach where the workload is spread out 'evenly' to everyone.
It is different from retail in the sense that you don't have waiters and everything is built around getting a run out. You will get used to it very quickly though.
At a very high level, it is basically the same as retail - orders come in, get typed, filled, checked, and then a driver takes it to the home. But there is a million times more drama around that process than in retail, in my experience. Also (perhaps related) LTC is orders of magnitude easier than retail. Although it is more time-consuming to fill a prescription in LTC due to how the medications have to be packed. That affects the techs more than you and you get used to it pretty quickly anyway.
