Micron Technology Process Engineer interview questions

I got an interview by submitting my resume at the conference career fair. Contacted by HR. Two rounds of interview. First round is interviewed by team manager, and second round includes director level and senior team member

It was an open interview. There were several positions opened on that day. Filled in details on an online form. I am a fresh graduate. I am not from electrical-electronics engineering background. So they did not ask me anything about the semiconductor-related.
