Micron Technology Administration interview questions

I interviewed with the recruiter and a HR person. Both made it seem that I should be grateful that I even got a call. The recruiter grilled me and I would answer the question correctly but would tell me that I did not give the answer I just did. I ended up passing that round. I then interviewed with the HR person who was very rude. She told me she knew my current executives and wanted to know details of each of them as to why I wanted to leave. I have an appropriate answer. I do not speak ill of anyone I have worked for. She brought up my past education and wanted to know why I didn’t pursue what I majored in. I gave an answer and she was not satisfied she wanted to know in detail why I didn’t want to get my masters. I felt very uncomfortable.
