I applied through an employee referral. The process took 2 weeks. I interviewed at Micron Technology in Feb 2011
Interview
The hiring process was very transparent and open. There was one HR interview and five to six technical interviews on ONE day. They judge basic device fundamentals along with some practical industry problems one may face being a process integration engineer. They asked some state of the art integration issues being faced in Advanced CMOS process Integration. Also gave some good overview of the whole group what it does and which other group it caters.
