I speak thru experience ts. Pinaka effective na approach ay wag puro describe sa sarili and sabihin mo like hobbies, what you do at home, where did you graduated from kasi it only makes them bored. Tell something that is unique. Just state your name, location and educational attainment that's enough. Your answer should focus on bringing an open question, yung kakasagot mo pa lang ay atat na sila mag follow up question, mahalaga na dala mo ang conversation para always comfortable ka sumagot and you know that the next question is still related to the first one if you caught their interest.
