Q. When did you start preparing for employment, and how long did the process take?
A. I started preparing for employment about one year before graduation. At first, it took some time to determine my direction, but I spent around six months preparing seriously by working on my resume, improving my technical skills, and practicing for interviews.
Q. How did you search for job opportunities and apply for positions?
A. I mainly used Korean job platforms such as Saramin and JobKorea. I also actively checked recruitment information shared through international student communities and student organizations. In addition, advice from senior students helped me decide which companies to apply to and how to prepare more effectively.
Q. What was the most difficult part of the hiring process, and how did you overcome it?
A. The most difficult part was explaining technical concepts accurately in Korean. To overcome this, I organized technical vocabulary separately and practiced repeatedly. I also participated in mock interviews with Korean friends to improve my speaking skills and become more natural in conversations.
Q. Why did you choose your current company?
A. The biggest reason was the opportunity to gain diverse hands-on experience by working directly with various products such as CCTV systems and electronic displays. I also believed that gaining experience not only in development work but also in technical certification and overseas-related tasks would help me grow professionally in the long term.
Q. As an international student, what do you think was your biggest strength?
A. Being able to use both Korean and Vietnamese was a major advantage. It was especially helpful in overseas-related tasks and communication. I also believe that my experience with different cultures helped me adapt quickly to new environments.
Q. Besides Korean language skills, what competencies did you prepare for?
A. I continuously studied embedded systems, networking, and IoT technologies while gaining practical experience through projects.
Q. Which classes or experiences at Kwangwoon University were most useful for employment?
A. Courses related to networking and embedded systems, as well as my capstone design project experience, were extremely helpful in my actual work. In particular, the experience of directly integrating equipment and systems significantly improved my practical understanding.
Q. What did you focus on when writing your self-introduction and application documents?
A. Rather than simply listing experiences, I tried to focus on how I solved problems and what results I achieved. I wanted to show that I was someone capable of working effectively in real situations.
Q. How did you adapt to Korean interview styles and corporate culture?
A. I practiced mock interviews with senior students and repeatedly reviewed common interview questions. I also watched YouTube videos and studied employment-related materials to better understand Korean interview styles.
Q. Was there a question you were frequently asked during interviews?
A. I was often asked, “As a foreigner, how will you adapt to working in a Korean company?” At first, it was difficult to answer, but over time I became more comfortable answering based on my own experiences.
Q. Were there moments when being an international student became an advantage?
A. Yes. In situations involving import/export tasks or communication with overseas clients, my language ability and global perspective became strong advantages.

A. The hardest part was preparing both language skills and technical competencies at the same time.
Q. Do you have any personal “survival tips” for studying and living in Korea?

Gain practical experience related to your major through projects or internships.
Actively communicate with people around you and gather useful information.
