Micron Technology Process Engineer (R&D) interview questions

First was a phone interview that lasted 30mins, with the hiring manager and his colleague. Technical (work ex related) and no personality questions.Was invited on site to Idaho at the end of the call with the trip expenses and accommodation paid for (also included a tour of the Boise city). Interviews were an elaborate and long process lasting the whole day (lunch included). Most of the questions from the leads/managers are prepared in advance, while the rest are impromptu (based on your resume and some fundamentals) Day typically starts with 30mins recruiter (just profiling), followed by two 1-1 30min sessions with engineers from the team the position is from (testing the fundamentals of the process applied for), Followed by hiring manager (mostly involving questions on prev work ex from your resume and some situations of how would you approach a certain technical challenge related to module applied for) and some surprise logic questions. This is followed by a lunch with lead engineer and a couple of other engineers, the interview process continues during lunch as-well. Lunch is followed by interviews two 30min 1-1 sessions with the leads (technical) and also involved a logic test (strange). The day ends with a short ivw with the group director (although it is short, the questions are bang on and you are left in awe as to how can a person be so spot on. ). The day ends with the hr assisting you out of the bulding. And rest of the evening you are left to ureself, pondering on your performance. Don't loathe yourself for not answering a few qs to your expectation although you knew them pretty well. It is humane to think of the wrong answers and their weight in negativity multiplies exponentially in ure mind as you keep thinking about it. I guess if you do well at about 75-80% of the questions you stand a pretty good chance. Thats about it folks, a 7hr process decides a short span of ure future.
