How do I figure out if a girl has a caring personality during an arrange marriage meet-up ?

Trip her little brother with ur legs, u can judge her caring-ness depending on whether she helps or laughs.

Ask her about her family and friends. If she is caring she will talk with warmth. How does she feel about going away from them post marriage, Her feelings for children, etc

Ask if she knows how to cook and loves cooking.

it take time and effort. It’s on how much time are you able to spend and know each other .
