Micron Technology Manufacturing Engineer interview questions

I applied for manufacturing engineer online and the interview came in one day. I think they are quite short-handed. I went there at noon. First was 30-minute test. It was about logic and intelligence. Then I went to my first interview with a senior manufacturing engineer. Quite standard questions. Then he passed me to the second interviewer. He repeated some questions and doubted my capability. Later, he passed me to their manager. He was nice and willing to know more about me. He showed interests in my past cca experiences and said I might be well qualified for this job. It was in total around 2-3 hours. However, I think my major is a bit too far away from manufacturing, I did not hear from them for around two weeks. I checked the online status of my application and I realised I was already "not considered".
