Micron Technology R&D Yield Enhancement Engineer interview questions

Applied online and met at a college career fair. Unsure of which got me the phone interview. Was emailed to set up a preliminary interview at a time that worked for me. Was awkwardly called an hour earlier than scheduled (their mistake not mine) and had to have them call back at the scheduled time since I was in class. I was asked simple questions, my strengths and weaknesses, why I wanted to work at Micron, etc.
