I was a very data driven dater, and I found that if you’re looking for a long term relationship then success looks like having common interests, common values, and common goals. Not all of them have to line up or be exactly the same, but there should be overlap and at least a lack of conflict in them. Common interests let you find ways to enjoy being together, common values help you make decisions that the each of you appreciate, empathize with and understand, and common goals mean that you are both working towards a future that the both of you will be happy with.
On dates I would ask questions that would get as much information about those things as I could.
