Micron Technology interview questions

I visited the college career fair and met with the Micron people who took my resume and indicated that there will be a presentation that night. I went to the presentation and they gave us pizza afterwards. They called me that night to set up a interview the next day. I did a one on one interview and they asked me questions regarding nmos gates, how they are set up and work and how to make logic gates using p and nmos gates, they also asked me questions regarding and, or and xor gates to debug a system. He indicated that his managers would decide if they would call me for an interview. I got the call after about a month and they paid for a flight and hotel to interview me. I interviewed with 4 people that were managers in the department. The asked me some similar questions, questions about semiconductors and hole vs electron carriers mobility and how to compensate for it, how a ac signal applied to an r-c circuit would look and how the voltage would change if you put a capacitor that was charged in parallel with another capacitor so that the charge would balance between the two and what the new voltage would be. Overall everyone was nice and helpful and positive.
