Micron Technology Process Engineer interview questions

3 rounds of interviews in a single day plus two written test. Take me the whole day to complete. The process was quite exhausting but the interviewers were nice. No technical question was asked. They seem to hire lots of people this year... Almost all my friends and I got the offer...

Very disappointed with the interview organisation. The company had called up over 300 people for interviews, all at the same time. The waiting time was absurd. There was no pre-screening of resumés. I was called for the first interview after 40 minutes of waiting. The interview lasted 1 hour and it went fairly well. At the end of the interview, the interviewer asked for my GPA. 10 minutes after the interview, I was asked to leave without any further explanations. The only conclusion I can draw is that they wanted someone with a higher GPA. But in that case, why not just pre-screen everyone by their GPA instead of calling down 300 people and wasting 4 hours of my time. Extremely unprofessional and absurd. Moreover, the interview was held on a Saturday.
