GE Aerospace interview questions

Give me a time when you worked with someone difficult?

She asked about the experience related to job descriptions. She were probing me on how my experience relevance to what they are looking for. It was very simple and none technical conversation. The next day were phone interview with the direct hiring manage who asked very technical questions. This is something that you know or you don't. Questions about heat transfer in a confine space. The manage was very kind and very direct. Later on, I felt like he was my mentor.
