First, there was a recruiter discussion (screening effort), followed by a call with a peer role. The call was about 40 minutes long, and focused mainly on my experience and a description of the position being applied for (all pretty straight forward). Feedback was tailored towards communication and thinking methodologies. The next call (committed to during the first call) was with the position's direct supervisor, and was structured much differently. It was more conversational, discussing in detail a technical challenge in my experience. The interviewer asked many probing and curiosity based questions, which seemed to be a conversational test of my knowledge and thinking strategy, as well as a performance of my communication skills. This call concluded with an invitation to visit the campus.
