The communities (theological) that do not have engaged couples see each other, generally have them meet only once or twice before they get engaged. There is not much of a relationship to maintain, so they wait until they are married. Usually, they are younger than in other circles, and their hands are also held by their parent for a while after the wedding, making the transition easier. Those communities have a different style of upbringing to begin with. It’s a completely different system than the one many are used to; to apply some of the features of that shidduch process in a vacuum would likely lead to disaster, but it seems to work for them.
