This is a telephone interview lasting around 15 mins. The HR mentioned he got lots of candidates to interview, so he spoke very fast. Firstly, he asked me to briefly introduce my background. Then, he asked a lot of details about my previous projects and coursework, such as "what is my MSc individual project", "what kind of development boards have you used", "What is most complex project using C programming language you had done". Finally, he asked me about the directions that I am interested in. He always showed his interests when I talked about different kinds of technologies. Overall, it is an nice experience.
