Phone interview: 30 minutes talking about the my experience and what to expect out of the internship. In-Person interview: I was interviewed by three different people -- each segment was 30 minutes. One was with my future manager, the questions were revolved around how I am as a worker. The second part was more math based questions so they can get a sense of my hard skills. The third part was about my personality so they can get a sense of my soft skills.
