I got three rounds of interviews including technical ones, then I had an interview with my potential team lead. The first thing he asked was about my MBTI personality test, which I hate and didn't pay much attention to learn mine. It seemed every encounter in Korea began with this MBTI test, but common in a job interview? I honestly answered him that I don't know my MBTI and just described my personalities in general. Then he started describing his MBTI and told me that I may not be the best fit with him because this and that.
A few days after, I got an email "... sorry". I don't want to believe that his MBTI question attributed a lot to this decision.
one project i am working with got a grant that was conditioned on the project being published as open source. it motivated the developers/researchers to reach out to the wider community and even package the project for a linux distribution. that's how i was able to find out about it. i got involved and i am still using it 20 years later. but without that grant this likely would not have happened.
