They asked me about my previous experience, and I explained the details of my resume, and why I did that kind of program or project, how I did initiate that program with what kind of background. And, they asked me if I had the difficulties to overcome, how did you access to that problem to solve it. And, they also asked me the future working plan, and what kind of technology will be important in the next 10 years.
It was great to have discussion about my area.
