There were 3 managers who interviewed. They asked regular interview questions, such as strengths/weaknesses, describe yourself, resume skills, etc. Majority of the interview was in Korean. It was obvious that they want someone who is more fluent in Korean. They did say they understand English so I can reply in English if I'm more comfortable. They explained that there's multiple teams per product and each team has a different way of operating. Near the end of the interview, one of them said he wanted to ask personal questions to "see how you would fit into my team" but you don't have to answer them if I don't want to. He then asked if I was born in the US, how many siblings I had, etc.
