Applied Materials Process Engineer interview questions

As a Ph.D. student I applied to Applied Materials through a job fair and could not get an on campus interview for a couple of reasons due to the Universities policy. I did not think about them until 6 months later when I got a call from a recruiter to have a phone interview. I passed the phone interview and was asked to come to California for an interview event. There were about 60 candidates at the interview event ranging from bachelor to Ph.D. The first day they told us about the company and gave us a tour. The second day were interviews. I had 6 interviews that day and others had anywhere between 1 and 6. The next day they called and offered me a job.

I was referred by one of my friend but I also applied online. I got phone interview invitation from 2 different engineering groups via email. There are 5~7 interviewers. It took around 15~20 minutes/each. The first interviewer was engineering manager, all others were senior engineers. All interviewers were nice. No difficult questions but they did ask some details about your research project and work experience.
