Samsung Electronics Engineer interview questions

Contacted HR through a job posting from school. HR responded right away with a few questions (making sure I am willing to work in Korea). Within a few days there was a phone interview. There was one person speaking English who was in direct contact with me. There were other people there who were not introduced. After every questioned answered, it seemed like she was translating it from English to Korean to them. There was also roughly a minute or so of Korean conversation happening. Questions were on why, why, and why. Why Samsung? Why Korea? Why this area? Also, they asked about my resume and a little about my research. After a thank you email, I waited a week without an update from HR. I emailed and found out I passed. The next step was an in-person interview. After a couple of months of planning the America visit, I met with a panel of 4 interviewers. The interview was only an hour and I was asked to present my research. Questions were primarily on my research and very little technical questions were asked. It seemed more like they wanted to get to know me. They were nice and friendly. Their English was very good. Questions were not too difficult. It was a very good experience for me. It took 1 month for them to make a decision or at least get back to me after follow-ups.
