Knowing one’s blood type is a big thing in South Korea.

A very interesting thing that is quite strange in Korea is the concern about other people's blood types. If you are not Korean, you will find this to be quite a unique thing here. For Koreans, blood type is a sign of an individual's personality and characteristics.

In conversations, especially dating, Koreans often learn about blood type first to learn about each other. If it's their blood type, they'll be more active in this conversation. For example, a woman with blood type B will tend to seek out a man with blood type O or AB but will stay away from a man with blood type A. Although not everyone believes it completely, this is also one of the criteria for them to choose their life partner.

Recently, Koreans tend to learn about MBTI (Myers-Briggs Type Indication) personality. This method uses questions aimed at testing psychological aspects, the personality of a person based on the basis of the personality. This test is the answer that the person chooses to the problems posed. Nowadays, many interviews include this question to see if candidates are a good fit for the position they are applying for.
