HR questions were fairly basic. The other 3 interviewers asked technical questions and did a pretty good job of explaining how their satellite systems worked. This was very exciting to me as I'm ex-Air Force and have direct hands on experience with navigational systems.
They asked me about testing methodologies, planning, and test case creation. They also asked how I defined end-to-end testing. They also wanted to know about my day to day testing activities at my current job. They ask about various test and bug reporting tools. The questions in both the phone and face to face were questions that were in line with a Systems Test Professional. The questions were fair.
