Korean interviews almost always open with a one-minute self-introduction. Improvise it and you spend the whole minute on background, never reaching your experience or your reason for applying. Treat this minute as a script you write and rehearse in advance, not something you assemble in the room.
Write it in four pieces
Open with your greeting and name in a single sentence, adding where you are from and nothing more. Then compress your field and experience into one or two sentences. Naming the role, the number of years and a concrete result works better than a narrative: three years of data analysis at an IT startup, a graduate degree completed in Korea. Third, add a short line on why this company and what you are like to work with. Close with a brief thank-you.
Rehearse it against a clock
Although it is called a minute, fifty to sixty seconds is what actually sounds right. Write the script, read it aloud and time it. If it runs over, cut the background first, not the achievements. Anything the interviewer wants expanded they will ask about, so the opening does not need to carry everything.
Modest, but say the thing
Korean interviewers tend to react badly to an introduction built entirely on self-promotion. The opposite failure is just as costly: being so careful that your actual strengths never get mentioned. Stating facts plainly sits in the right place between the two. Your Korean does not need to be flawless, but opening with a short polite greeting in Korean noticeably warms the room, and it is two seconds of the minute.
The two questions that follow immediately
Once you finish, why you applied to this company is close to guaranteed. The smoothest route is to expand something you touched on in the introduction, which is a reason to plant a hook there deliberately. The other question foreign applicants get often is whether they plan to work in Korea long term. What sits behind it is a practical question about your visa and how settled you are, so answering with your residence status plan and your Korean study addresses what they are actually asking rather than sounding evasive.
