At ours we gathered inconspicuously at the wing building at a designated time a few days before graduation, some realizing for the first time who all was actually in their class. Then one at a time, while the rest waited in a conference room, and based on class ranking, we were called in one by one to an office down the hall to select our assignment from the drop for our class. Then when it was all over, we left individually, going separate ways (in my case to the LL/TF checkride brief), most likely talking on cell phones. The camaraderie was brilliant.
