Phone Interview with Shell

I had a 20 minutes phone interview with Shell at 2pm, today. I was very nervous before the interview. A lady from the Human Resource (HR) called me slightly after 2pm. Unlike other interviews, she did not ask any technical questions. Instead, she asked questions on leadership, achievements, problem solving and challenges. The weirdest part is the last one, about general knowledge. She asked me about National Park, its purpose, advantages and disadvantages. Even though it is not a face-to-face interview, I feel even nervous, maybe because I could not see her reactions on my answers. I will be notified if I manage to get into the last phase of interview in another 5 working days. According to the lady, there would not be any technical questions for the last phase as well. It will be a whole day session in Shell.
